Fantail Goldfish - Carassius auratus

Fantail Goldfish (Carassius auratus) are fancy goldfish suited to an appropriately sized, well-filtered aquarium. Choose compatible companions that will not outcompete them for food.

Ideal Tank Mates

These tranquil goldfish thrive when housed alongside other fancy varieties like Ryukin or Black Moor. It is advisable to avoid placing them with faster or more aggressive fish that could dominate feeding. Keeping them with similarly slow-moving species promotes a peaceful environment and minimises stress.

Feeding and Nutrition

Fantails are omnivores needing a well-rounded diet. Their main food should consist of premium goldfish pellets or flakes. Enhance their nutrition with live or frozen options like brine shrimp and bloodworms, plus blanched vegetables such as peas or courgette. Offering small, regular feedings supports healthy digestion and helps avoid overfeeding.
