If so:
1. Tank size? 300 (72x36x27) I would recommend at least a 24" wide tank. At 15" they need a lot of room to swim
2. Temperature? 82
3. Food? Massivore, nightcrawlers, smelt, shrimp
4. Tankmates? P-bass, red hook silver dollars, Leo/Hen ray
5. Group size? just one
My guy grew pretty fast when I put him on a 24/7 drip but rather slowly with less frequent changes. He slowed down around 15".
He can get a little pushy with anything flashy or white (mag float algae scrubber lol) but has never messed with any rays or p-bass
6. Pics?
This is him 4-08-2011 at about 3" when I got him
