actually he is growing at a fantastic rate! he has literally put on inches since the purchase. He lost a little nip of his tale from a gachua, but other than he's been great! I'll post side by side pics tonight to document the growth! His mouth opens so wide for some larger feeders, its almost alarming!! I love it though, very intersting fish, and fits right in with the "predator tank"! Only downside I might have to remove my marbled goby, he isnt growing near fast enough to keep himself out of that mouth! I keep seeing him get close then back off!
