Catfish are a vital part of a healthy tropical aquarium, known for their unique character and cleaning abilities. Most are peaceful, nocturnal bottom-dwellers that use their sensitive ‘whiskers’ to find food. It’s crucial to provide them with sinking pellets and hiding places like caves or driftwood.

When choosing, always check the final adult size to ensure they suit your tank.

Top Choices for UK Hobbyists:

• Corydoras (Corys): Small, sociable, and peaceful. Must be kept in groups of 5 or more.
• Bristlenose Pleco: A brilliant and hardy algae-eater that stays at a manageable size (around 4-5 inches).
• Otocinclus (Otos): Tiny, gentle algae-eaters, perfect for smaller planted aquariums. Best kept in small groups.
