I went to my local fish store and bought a bumblebee catfish, but the label on the tank was very confusing. It claimed it was the Microglanis iheringi, which implies a 2.5 inch max size. Next to this name though it claimed it grew to 10 inches, refering to Pseudopimelodus bufonius. Naturally this very small catfish hides alot so I cannot get a good picture. How can I tell if this cat will grow to be a beast or just a few inches?
