Bubba, a 29g is too small for a dwarf lion. I would say a 55 would be the minimum size. You've got to remember, while they might not grow to long, their long, flowing fins do require space. As for long nose hawks, they aren't as agressive as other hawks, and do well in a reef or f/o environment. They will eat brine, mysis, prime reef, etc., and maybe some flake foods. The hawk and clown would be great in a 29, but scratch the lion. Bo
