Penguin Tetra

Sold out

Penguin Tetra (Thayeria boehlkei) comes from the upper Amazon River Basin and feeds on small worms, insects and crustaceans in the small streams in which it is found. They need to be kept in a school of 5 or more and with similar sized tank mates.

The Penguin Tetra is usually olive with a prominent black line running down the lateral into the lower half of the tail fin, and its belly is silver colour. This species unusual swimming/resting motions can be quite eye-catching, and give the fish a strong sense of individuality amongst similar sized tank mates.

Penguin tetras feed on worms, insects and crustaceans. Try to reflect this in their diet by offering lots of suitably sized live or frozen food such as blood worms, glass worms, daphnia, cyclops and brine shrimps. Using a good quality flake food with these will ensure a good balanced diet.
