I got a South American Bumblebee Catfish some time ago. He was going to live in the guppy tank. Actually, I hoped he would eat some of the guppy fry. All my attempts to reach that goal before that were futile. My rams or the gourami don't eat tiny fish
. The guppies don't, either. Only the huge amano shrimp catches one or the other. I didn't see any effect from the cat so far.
Anyway, back to the question. How big do they really get? Do you think they will get that big that they eat a panda cory one day? I just ask, because I want to be better safe than sorry.
