I picked this guy up labeled as a blue mystus cat but can't seem to find any information or adult pictures. Does anyone keep them, know how big they get, or know anything about them? Sorry for the terrible picture.
Also pay attention to how many pictures there are for each species (it is easier to scan for the pic number in this list, scroll down to Mystus http://www.planetcatfish.com/common/family.php?family_id=8 ). I'd only be concerned with the species with the most pictures, if there is none or 1-2 pics, that most usually means they are very rare and chances are you'd never get them.
