I had a big Goldie I name Frankie. I got him at 12", and he grew to 13.5" before he died. He lived with discus, and could not have been a better match. He was so well behaved, and since they were all such slow eaters he got to eat in peace. Seeing your little guy makes me miss my gentle giant so much. When I again have an appropriate home for one, I'll definitely be getting one. He was very much a carnivore. Didn't take to veggies hardly at all. I hope your little guy does well.
