Yeah, mines not nearly that big. I mean it still looks like a baby. I've had it for like 5-7 months. It's grown a little but not like yours. I have him in a about 15 gallon tank, a good filter, and light. I feed him , baby feeders, pellets, worms, moths, bugs etc. Maybe his tank is too small. Do they only grow to there tank size, like fish? Whats yours in? Any ideas why hes smaller? Thanks alot.
