I recently bought a Raphael Catfish. I knew they were fairly shy and stayed hidden most of the time, but I can't seem to find him...ANYWHERE. I have even moved all my decor around, but no sign of him. Would he have buried under the rock?
be careful when moving the decor around...you don't want to crush him by accident. He's got to be in there somewhere. take a flashlight at night to try to find him, just a suggestion.
basically if you see it during the day it is really hungry, do you have any decor with "cave" openings, mine almost always wedge themselves inside a sunken ship or log and even if decor is pulled out of the water they will stay put/
