Ive got a 20 gallon tank containing a pair of clowns, a royal gramma, 4 nassarius snails and 4 trochus snails. Ive seen at my lfs flame and longnose hawkfish and absolutely love them. I understand not all hawkfish like snails and will be setting up an 8 gallon reef so if i had to i could house them there. Is it possible to have one in a 19 by 14 by 14 inch tank?
