Aries (21 March – 19 April)
Those born under the fire sign of Aries the Ram are renowned for their assertive, adventurous nature. These folk typically love challenges and are natural leaders. For these fiery personalities, fish with an independent, bold personality make the most harmonious partnership.

Siamese Fighting fish or bettas have a strong, independent nature, making them the perfect match for the assertive, bold Aries aquarist. Bettas have gorgeous, vibrant colors, making them a beautiful addition to your community.

Swordtail (Xjiphophorus hellerii)
- Temperature range 72 to 83°F (22 to 28°C)

Taurus (20 April – 20 May)
Those born under the earth sign of Taurus the Bull are peaceful souls who enjoy relaxing in serene environments, surrounded by soft sounds and soothing scents. This star sign is ruled by Venus, the planet that governs beauty, love, and money.

Choose from speedy Shubunkins and Comets for an outdoor fish pond, or pick one of the beautiful varieties of round-bodied fancy goldfish for a spacious aquarium with efficient filtration.
Corydoras Catfish (Corydoras spp.)
- Temperature range 72 to 78°F (22 to 26°C)

Corys are peaceful bottom-dwellers that make the ideal addition to a Taurean’s peaceful community fish tank. These delightful little fish come in myriad varieties, are super-easy to care for, and do best when kept in small groups. Over the years, I’ve always kept Corys in my tropical tanks. However, they will also tolerate slightly cooler water temperatures and have lived happily with fancy goldfish.
Gemini (21 May – 20 June)
Geminis are curious, communicative, adaptable air signs who need lots of variety and intellectual stimulation in their lives to be happy. An aquarium curated for Geminis must be full of colorful, dynamic, and diverse fish species to mirror this star sign’s multifaceted personality.

People born under the star sign of Cancer are renowned for their empathetic, nurturing nature and love of family. Those born under this water sign are best suited by an aquarium with a homey, comfortable vibe featuring fish with non-aggressive, gentle temperaments.
Platy (Xiphophorus maculatus)
- Temperature range 70 to 77°F (21 to 25°C)
- pH 7.0 to 8.0

In that case, you can expect these livebearers to reward you with swarms of tiny fry regularly, fulfilling the Cancer’s love of family.
Kuhli Loach (Pangio kuhli)
- Temperature range 75 to 86°F (24 to 30°C)

Leo (23 July – 22 August)
Leos are known for their confident nature and leadership skills. A tank specifically curated for this fire sign should feature fish with vibrant colors and bold personalities, reflecting the grandeur of the lion that represents this zodiac sign.

Bristlenose Pleco (Ancistrus spp.)
- Temperature range 60 to 80°F (15 to 27°C)
- pH 5.8 to 7.6
- Water hardness 6 to 25 dGH
Bristlenose plecos are quirky to look at and can add an intriguing element to a fish tank. These fish can thrive in an aquarium with plenty of suitable hiding spots like caves and dense, busy planting. As a bonus, the Bristlenose pleco helps to keep your tank looking tidy by grazing on algae.
These fish can tolerate a lower water temperature, making them potentially suitable for life in a goldfish tank.

- Water hardness 6 to 12 dGH
With its understated colors and peaceful temperament, the elegant Pearl gourami can add a sophisticated touch to any Virgo tank! These fish can grow up to 5 inches in length, so you’ll need a relatively large, spacious aquarium to accommodate them.
Pearl gouramis generally do well in a community tank with other non-aggressive fish of a similar size. However, I found that keeping several males didn’t work so well, since these fish can be territorial, especially if spawning. Ideally, you should keep one male with a group of females for a harmonious setup.

Libra is an air sign represented by the scales. That image reflects Librans’ sociable, balanced, aesthetically inclined nature. These guys prefer a well-maintained, harmonious tank featuring peaceful fish species that boast vibrant colors.

Gouramis are labyrinth fishes that need to visit the water’s surface periodically to breathe atmospheric air via their labyrinth organ.

Although often mistaken for a fire sign, Scorpio is a water sign with an affinity for aquatic creatures, so it’s no surprise that many Scorpios keep fish.

- Temperature range 72 to 82°F (22 to 28°C)
- pH 6.5 to 7.5
- Water hardness 2 to 15 dGH
