Species group: Tetras
Other common names: Penguinfish
Scientific name: Thayeria obliqua
The Penguin Tetra is a small schooling fish which is native to densely vegetated streams in the Amazon, Rio Guaporé and Rio Tocantins basins in Brazil.
Penguin Tetra make good community tank fish, and do well with other species of tetras and other small fish which are not large or aggressive. They are schooling fish and usually kept in shoals of six or more. This makes them happier, more active and colorful. A lonely Penguin Tetra becomes stressed and goes into hiding. Being timid by nature, housing them with large or aggressive fish is not safe.
Penguin Tetras are best housed in a tank with a capacity of at least 10 gallons. Sudden changes to the environment is best avoided. These fish thrive in a well-planted tank with dim lighting. Driftwood may also be provided.

Copper works when dosed correctly
Copper sulfate is a heavy metal that when dosed correctly, kills Chilodonella. The idea is to kill the parasite and not harm the fish. Dosing is based on the alkalinity (carbonate hardness) of the water. Copper toxicity increases as carbonates decrease, so a lower dose is required in low-alkalinity water. Charts can be found online. You'll need a copper test kit and alkalinity test kit to dose in the best manner. Otherwise, follow the directions on the treatment label.Avoid chelated or complexed copper medications. They are not effective..
