Update! He's easily grown an inch already and is an absolute vacuum. Around 7" right now and always fat. Also one of my hardest fish to get pictures of since he is always hiding on the backside of the driftwood or cruising around looking for more food, even when he does stop he doesn't hold still. I recently added some leaf litter and he seems to enjoy digging through it and putting his "shovel" to work finding pellets and shrimp
