Indian Almond Leaves | How and when to use them!

June 1, 2014
indian almond leaf

If you’re an aquarist, you’ve probably heard of Indian almond leaves (also known as Catappa leaves). These leaves of the Terminalia catappa tree are especially popular in the betta and shrimp hobby as a natural medicine and water conditioner. They are said to help combat fungus and bacterial problems like finrot, and prevent stress by mimicking the natural habitat.

But how, when and why should you use them?

What are Indian almond leaves?

As mentioned before, Indian almond leaves are the leaves of the Terminalia catappa tree, which grows in large parts of Asia. The leaves are usually harvested by simply picking them off the ground. After drying them, they are ready for use in the aquarium.

You can importย Indian almond leaves directly, but nowadays they are also available in some pet-/aquarium stores and online!

What do Indian almond leaves do?

When placed in an aquarium, Indian almond leaves slowly start to decompose. While this happens they turn the water a yellow or brown color by releasing tannins. These tannins lower the pH and are said to have antifungal and antibacterial properties, which comes in very handy when you have a fish suffering from finrot or when you’re raising vulnerable fry.

The dark color of the water is considered unsightly by some aquarists, but it actually mimics the natural habitat of many fish species! This definitely makes it something to consider embracing.



When should I use Indian almond leaves?

Indian almond leaves are especially popular in the betta and shrimp hobby but can be used in many situations.

  • Adding a few leaves to a quarantine tank with a sick fish can help speed up the healing process; I’ve spoken to betta breeders who have actually stopped using regular fish medication altogether and treat sick fish with nothing but Indian almond leaves and clean water.
  • When you’re dealing with fish/invertebrates that prefer soft, acidic water, Indian almond leaves can also be great for stimulating breeding. The tannins released by the leaves help create water conditions that are similar to those in the natural habitat of the fish, which means ideal breeding conditions. If you’re trying to get your bettas or Crystal Red shrimp to breed, adding a few Indian almond leaves to the breeding tank can speed up the process!
  • Lastly, there are also situations where Indian almond leaves can be added to the aquarium purely because of the way they stain the water. If you’re interested in setting up an Asian blackwater biotope, which imitates blackwater rivers and streams, Indian almond leaves are a must have. They appear in these regions naturally so they are biotope correct. You can also add the leaves to other aquarium setups with fish that prefer soft, acidic water if you like the look of it.

How do I use Indian almond leaves?

There are a a few different ways to use Indian almond leaves; the easiest is to just place them in the aquarium and wait for them to do their job. The more you add, the darker the water gets. You can tear the leaves up if you want the tannins to release more quickly. Once the theyย start decomposing you can take them out or replace them, but it’s also fine to wait for them to be completely decomposed. Shrimp will actually appreciate it if you don’t remove the leaves, as they feed on the decomposing remains.

If you’re not a big fan of leaf litter in your tanks, another option is to soak the leaves separately and adding the stained water while doing a water change. You can also make your own blackwater extract, which is a concentrated version of stained water. This is done by taking a very large amount of Indian almond leaves, boiling them in a pot of water and letting them soak for multiple days afterwards.

You only have to add a small amount of the extract to your aquarium to get that blackwater look. (And by the way, if you’re not the kind of person who stands around boiling leaves, you can also just buy your Indian almond leaf extract. We don’t judge.)

Seed pods, twigs, alder cones and other litter

With the popularity of realistic blackwater biotope aquariums ever-growing, so is the amount of different types of dried tree bits sold by aquarium companies. Most aquarium stores nowadays not just sell the classic Indian almond leaf but might carry many other different types of litter that you can use in your tank.

Generally speaking, all of these products have the same beneficial effects as Indian almond leaves. They release beneficial tannins and help create a natural look that your fish will appreciate. So switch it up!

How about some banana-, magnolia-, oak-, mulberry- or guava leaves? Or maybe seed pods from various plants like alder cones (much appreciated by dwarf shrimp), magnolia or lotus? If that’s still not enough, you could even try twigs and bark like that from the Indian almond tree, palm fronds, or plain old oak twigs.

Some of these items you can collect yourself if a certain tree grows near you. Do keep pollution in mind, though: clean any leaf litter before using and avoid anything that’s growing in polluted areas.

    Hello, just today I’ve bought a IAL. Right now is inside my aquarium. I do not know if the properties of the Almond leave will disapear if I have active carbon in my filter. Do I have to remove it or keep it in?

    • ReplyMariNovember 26, 2018 at 4:56 pm

      Active carbon does remove the beneficial properties of IAL. In fact, it’s not a good idea to have it in your filter on a permanent basis at all. In a healthy and cycled aquarium it won’t be needed and it actually removes other beneficial substances from the water as well. I recommend taking it out and keeping it for emergencies or to remove medication from the water if the need arises! ๐Ÿ™‚

    Hi, I have a male veil tail Betta and he has been experiencing some bloating for about a month now. I tried giving him a raw pea and fasting him but the bloating just hasnโ€™t gone away.
    I was wondering if adding the IAL would help the bloating go down. What would you suggest?

    • ReplyMariNovember 10, 2018 at 3:50 pm

      Hey! If he’s still bloated after a month then I think it might be something more serious than can be solved with some IAL. Have you done a thorough check of your water values and other factors? There are a number of reasons for bloating beyond just diet, some of them a bit more grave unfortunately.

      That being said, adding IAL is still pretty much always a good idea with Bettas, so you can still go ahead and do it. Just don’t hold too much hope of it solving the problem altogether.

      Hope he recovers!

      PS: peas aren’t good for Bettas as they can’t digest them. For bloating problems that are related to diet you can feed daphnia or try an epsom salt bath. ๐Ÿ™‚

    Hello, thankyou for your helpful article. I am planning on using these for my discus and angelfish aquariums which are 75 gallon and 110 gallon. My intention is to boil the leaves to make extract. My question is how long does the extract keep for? and should I store it in the fridge?

      With the acidity level of these extracts I’d expect them to keep reasonably well, especially in the fridge. What I’d do, though, is just freeze it in handy amounts. Then when I’d need it I could just thaw and add to the tank the amount that works for me! ๐Ÿ™‚

    Hello!
    I have a half moon make betta in a 5 1/2 gallon tank. He has been fail biting and I have 7-12 inches of almond leaves. How many should I put in his tank? In addition, should I boil the leaves and let it cool and dump everything in Ghosteโ€™s tank?
    Thank you!

    • ReplyMariOctober 15, 2018 at 10:05 pm

      Hey! Sorry to hear your Betta has been tail biting.

      You could start by just putting one leaf into his tank, in a 5 1/2 that should already have some effect. You can always add more after that if you’d like the water to be darker. Boiling the leaves to make extract that you can add a little bit at a time of is something you can do, but not a necessity. It just depends on your own preference. I think your Betta will appreciate the leaf litter in the tank so I’d go the other route of just putting the leaf in instead.

      Keep in mind that the leaves float at first, which is not a problem. Good luck!

    Hi. I have a betta in a 3.5 gallon (yes I know, small. I can’t afford bigger at the moment) with snails and a marimo moss ball. Will the leaves harm my moss ball at all? The snails and betta love it so I’d hate to see it damaged. My betta has a tail nibbling problem and I’m hoping maybe the new moss ball addition and the leaves will help calm him down a bit. He does it when I’m not home or when the water temp isn’t just right, I’ve caught him in the act. Definitely not fin rot (yay) but not sure what to do with him.

    • ReplyMariJuly 16, 2018 at 5:35 pm

      Hi,

      The leaves won’t hurt your moss ball in any way whatsoever, so yay! And I think adding some decor will definitely be appreciated, so that’s a good idea. You could also consider floating plants, I’ve got an article with some info on them here.

      Good luck, hope he’ll stop tail biting. Such a frustrating thing!

    Hello!

    Iโ€™ve been using these in my betta tanks and noticed recently that they start to grow fuzz on them in different spots a couple days after adding them. If I scrub it off it just comes right back. Would you have any idea what this is or whatโ€™s causing it?

    • ReplyMariFebruary 10, 2018 at 10:36 am

      Hi! Yes, your leaves are decomposing as they should be and the fuzz is biofilm ๐Ÿ™‚ it should be completely innocent. Shrimp keepers would be jealous of you, they deliberately grow this stuff in their tanks to feed their shrimp!

    Iโ€™m so happy I found your site! You have shared such a wealth of knowledge. My question for you is I just moved my 1 female beta and 2 tetras into a 13 gallon from a 3 gallon. I had the water tested prior to moving them in and everything was perfect according to Petco. All 3 fish are really active and eating well. My concern is the beta may have fin rot. Since sheโ€™s a female and has smaller fins than the males Iโ€™m just not sure. She also looks like she has some dark (almost black) spots are her body. Sheโ€™s darker blue so itโ€™s hard to see them clearly. Should I separate her from the 2 tetras? Do you think IAL would help? Thank so much for your advice.

    • ReplyMariFebruary 9, 2018 at 9:35 am

      Hi,

      Nice to hear you’ve upgraded your Betta, I’m sure she loves having so much room!

      First off, I’m sad to say NEVER trust anything you hear from a chain pet store. More often than not, employees know absolutely NOTHING about keeping fish. Did they give you the exact water values? Did you cycle the tank before moving the fish in there? Is there a specific reason you don’t have a liquid test kit yourself (you should really have one if you want to keep fish, especially if you think you’re dealing with something like fin rot)?

      If the tank is fully cycled and the water quality really is good, the instructions in this article should be enough to work things out. IAL is also always good, whether your Betta is sick or not. If the tank isn’t cycled then you’re unfortunately in a bit of trouble here. Let me know if that’s the case and do daily water changes until you hear back from me.

      Lastly, yes, separate her from the tetras. Those are group fish that should be kept with at least 8 and shouldn’t be kept with Bettas because their activity level and nippiness can stress them out.

      Hope things work out and your fish will be fine!

    Will these leaves cure my baby (full grown Betta) of his graying fin rot. Got him from Walmart. Or should I just do aquarium salt baths? He has gray on his torso and his find are fading at the ends. Betta Fix doesn’t seem to be working.

    • ReplyMariOctober 28, 2017 at 9:54 pm

      Bettafix isn’t working because it isn’t actual medication, it’s a mild antiseptic and it’s actually not suitable for Bettas despite the marketing. It’s just diluted tea tree oil. Indian almond leaves won’t cure your Betta but they can help create a healthy environment (as long as the rest of the tank is suitable – filtered, cycled, heated, 5+ gal). If you’re sure it’s fin rot you’re dealing with, don’t use aquarium salt – it doesn’t work either and actually harms your fish. Go for an actual antibiotic like Maracyn 2. I’ve got a full article on dealing with fin rot here but I must warn you that if the rot has spread to the body you might not be able to save him any more.

      Good luck! And be sure not to buy any fish from Walmart any more. ๐Ÿ™‚

    Hi, I’m just wondering how drastically one leaf could change the pH in a 10 gallon? My tank pH is a constant 8.2, but I want my future Betta to be as comfortable as possible. The main thing I’m worried about is that when I do water changes the pH will shoot back up from the fresh water and shock my Betta

    • ReplyMariAugust 30, 2017 at 12:10 pm

      One leaf doesn’t change the pH drastically at all so that won’t cause any problems ๐Ÿ™‚

      If you really want to go the blackwater route but are worried about water value fluctuations you can always make blackwater extract and add that to the new water before fillng the tank back up.

    • ReplyMariMarch 16, 2017 at 9:23 am

      You don’t necessarily have to use Indian almond leaves, many leaf types and other plant parts are used to darken the water. I think other almond tree types are fine but be sure to check their toxicity beforehand. You can also use oak leaves!

    Does the extract have the same medicinal effect as the leaves? and how do you tell how much of the extract to add? (10 gal tank, betta fish)

    • ReplyMariFebruary 26, 2017 at 6:38 pm

      Yes, the extract has the same effect. I can’t really tell you how much to add, that also depends on how dark you would like the water to be. You can just carefully add extract until it looks dark enough to you. You can assume you’re getting the positive effects as soon as the water is starting to look tea colored/yellowish.

    • ReplyHarryMarch 16, 2017 at 9:38 am

      The recommended dose to make your own extract is to boil 50 grams of (crushed) leaves in 2 liters of water. After 2x boiling you finally will get aprox. 1 liter of extract. From this extract you add 10ml for every 10 liter water (2.5 gallon). So in your case that would be 40ml for your 10 gallon tank. Thats how i use it for my discus and they love it.

    In my 10gal tropical community tank others fin rot. I have 1 male betta 4 corys and an otocinclus. I hate using medications and was wondering how well Indian almond leaves work for fin rot. And how any do you put in a 10gallon to treat fin rot? It’s not server yet but bad enough. Thank you!

    • ReplyMariFebruary 16, 2016 at 8:39 pm

      Hi! What kind of Cories do you have? It sounds like your tank may be a little overstocked which is likely causing the fin rot. I’d recommend rehoming at least one species – if the cories are anything other than Corydoras pygmaeus, hastatus or habrosus then it’s really a good idea to find another home for those. You can then expand your group of Otocinclus, they prefer to be with at least four or five and don’t have a very high waste output.

      As for treating fin rot with these leaves, they don’t replace medication but can help if there is no very serious damage yet. Beginning fin rot can be treated with a combination of very clean, warm water (daily water tests with your liquid test kit, increase your water changes) and possibly some Indian almond leaves. Three leaves would be a good starting point, don’t be scared if they discolor your water. If the fin rot keeps progressing you’ll unfortunately likely have to switch to antibiotics. However, as the fin rot is likely caused by overcrowding I suspect you won’t have too many problems with it once you’ve rehomed a few fish. 10 gallons is very small and can only be stocked very lightly!

      Good luck! I hope everything turns out alright.

      I think the shrimp like to eat the leaves, but other than that there is no benefit if you’re also using carbon (unless it has already lost its effectiveness, which doesn’t take too long). In a 100 liter, one leaf isn’t going to do much, though, you’ll definitely need to use a few more to actually see a difference. Good luck!

    I’ve had live plants in my tank before but the fish started to eat the plants and that killed the plants. Is it safe for fish to eat the leaves? Once the leaves start breaking down do they release any sort of ammonia?

      I think you could use the leaves if you want to; they do of course release some wastes while breaking down, but you should not experience any problems. Many people actually let them break down completely, but if you’re unsure you can remove them timely to prevent any possible issues. You could start with one leaf and see how it works! You can also use almond leaf extract so you don’t need the actual leaves.
      I’m just wondering how big your setup is, though? The sharks especially need a very big tank and are semi-aggressive, so unless your setup is quite big there may be aggression in the future.
      Good luck!

    Well, I am definitely getting these. A few quick question- How do I tell if they could be carrying a disease, or something that could harm my fishies?
    And would neon tetras like these? I know they come from slightly more acidic water, and don’t think they would dislike them, but I do want to check.

      If you order from a trustworthy site you can be 99% there are no pesticides/diseases on the leaves! I have never had problems with it. Neon tetras do like Indian almond leaves, so you can definitely try them if darker water is not a problem for you ๐Ÿ™‚

        Great, Thanks! Darker water is not a problem for me, as I think it looks sort of pretty when you are doing certain aquascapes. My fish will have to wait a while before I can get them(I’m thirteen, and my parents don’t believe in buying stuff like this, so I have to wait until Christmas) Hopefully by that Time I’ll have had my Divided betta tank set-up, so all my bettas can have IAL, as well as my neons.

    Hi there! I just want to say that I love your blog so much and ive been following you ever since it was just your goldfish tumblr. I’m from the Philippines and indian almond trees grow everywhere, i would just like to know if there is any actual difference between handpicked and dried leaves and naturally dried leaves because there seems to be conflicting opinions online and id feel much more comfortable asking you hahaha. Thank you so much!

      Hi! That’s actually so great to hear, thanks for messaging me!

      I’m actually unfortunately not sure if there is a difference, although I don’t think so. I think I’ve used both and I’ve never noticed any difference. Just be sure to pick the big “adult” leaves and I think handpicking is fine!
