Chinese Algae eater |Pair

The Chinese Algae Eater (Gyrinocheilus aymonieri) is a freshwater fish known for its algae-eating abilities, though its temperament changes as it matures. While commonly sold as a tank cleaner, it requires careful selection of tankmates due to its potential aggression as it grows.

Key Features:

• Scientific Name: Gyrinocheilus aymonieri
• Size: Can grow up to 10-12 inches (25-30 cm)
• Lifespan: 5-10 years with proper care
• Temperament: Juveniles are peaceful, adults become territorial
• Swimming Level: Bottom-dweller

Tank Requirements:

• Minimum Tank Size: 30 gallons for young fish, 55+ gallons for adults
• Water Parameters:
  • Temperature: 74-80°F (23-27°C)
  • pH: 6.5-7.5
  • Hardness: 8-12 dGH
• Filtration & Setup:
  • Strong filtration for clean, oxygen-rich water
  • Rocks, driftwood, and caves for hiding spots
  • Live plants, though may uproot delicate ones when mature

Diet:

• Omnivorous: While young fish eat algae, adults require:
  • Vegetable-based foods (blanched zucchini, spinach, algae wafers)
  • High-protein treats (bloodworms, brine shrimp, pellets)

Tankmates:

• Best with semi-aggressive or larger fish (barbs, rainbowfish, cichlids)
• Avoid:
  • Slow-moving, long-finned fish (bettas, guppies, angelfish)
  • Small, delicate fish (tetras, rasboras)
  • Other bottom-dwellers (corydoras, loaches) due to territorial behavior

Ideal for:

• Experienced aquarists who can manage their changing temperament
• Large community tanks with robust, fast-moving fish
• Tanks needing algae control (only when young)
