Hi I'm new to the fish forum and wanted to know if this is an odd occurence or not. I recently had to remove the most deranged killer Leporinus fish from my tank (hes in solitary now) as he killed many a good, and expensive fish! Well the entire time he was in the tank, my Angelicus hid by digging his own cave and never coming out. Since he left the Angelicus started coming out more often but always steered clear of every other fish. I just got a Raphael Catfish and as soon as he was in the tank he claimed one of the caves in my tank and hasn't moved since, but as soon as the Angelicus saw him, he buddied right up with him, and hasn't left his side yet. Does anyone know if the two species are normally like this, or what.
