Peacock Gudgeon

Peacock Gudgeon stands out in 10- to 20-gallon communities where you want a small fish with a little more presence and display behavior.

Peacock Gudgeon (Tateurndina ocellicauda) fits especially well in planted 10- to 20-gallon aquariums with calm tankmates, wood, and visual breaks. It works as a small focal fish rather than a hyperactive schooler, which makes it useful in aquascapes that need personality but not crowding.
