Oddball is a loose basket term for all the unusual fish species that don’t quite fit into the generic families and categories that are most commonly kept in the home aquarium.
They can also be called Monster Fish if they reach over a certain size. Fish like Electric Eels, Piranha, Arapaima and Pufferfish are all considered oddballs. Learn what goes into keeping these unusual fish in our series of guides on Oddballs and Monster Fish.
