Im not sure on his age, I had a spell where he wanted to eat fish but has calmed down for now. He is with 5 P-bass, 2 18"-20" Arows, and a shovelnose.
This pic was taken 1 year ago and he is alot bigger now. His shell is around 14"-16". He wouldnt fit in a 125 anymore. He currently lives in a 350 gallon.
