Aries (21 March – 19 April)

  • Temperature range 78 to 80°F (25 to 27°C)
  • pH 6.5 to 7.5
  • Water hardness 5 to 20 dGH

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. However, although the betta fish’s territorial, aggressive personality aligns with Aries’ leadership traits, you need to choose their tank mates carefully to avoid confrontation.

Swordtail (Xjiphophorus hellerii)

  • Temperature range 72 to 83°F (22 to 28°C)
  • pH 7.0 to 8.4
  • Water hardness 12 to 20 dGH

Swordtails are active and curious fish that can appear to Aries’ adventurous side. The brightly colored orange and red coloration of these striking fish reflects the fiery nature of this zodiac sign.

This species does best in a moderately sized tank with plenty of hiding spots. They’re generally peaceful and can live in a community tank, often spawning spontaneously when provided with the right conditions.

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.

Taureans appreciate stability and reliability, and their patient, determined nature makes elegant, peaceful fish the perfect choice of aquatic companions.

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)
  • pH 6.0 to 7.5

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.

Platys are peaceful, easy-going fish that make excellent pets for Cancerians. These fish come in a dazzling array of shimmering, metallic colors to add a touch of joy to the tank and create a truly comforting environment. Suppose you offer your fish an optimal environment. 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
  • Temperature range 75 to 86°F (24 to 30°C)
  • pH 5.5 to 7.5

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.

These fish can tolerate a lower water temperature, making them potentially suitable for life in a goldfish tank.

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.

Pretty much all gourami species, with their peaceful temperament and understated colors and patterns, can do very well in a beautifully decorated community setup with other non-aggressive fish and invertebrates.

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

These active little fish thrive in a peaceful community setting and can live in a relatively small 20-gallon aquarium with other similar types.

Scorpio 23 October – 21 November

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.
