QuestionHow big in length can a pacostamus get?
AnswerHi Dru,
A Plecostomus Catfish can grow to 18 - 20 inches They eat algae, and must be fed pellets that are made especially for them. They cannot survive with eating algae only...they must be fed pellets made for bottom fish.
A Pacu can grow to 30 inches long.
I wasn't sure which fish you meant. The Pacu is a relative to the Piranha, a beautiful fish that can live for 20 years if well cared for. He is of the Tetra family. They are vegetarian, but provide a varied diet. They are not aggressive, but will eat small fish.
