i was thinking about getting a 12g nano set up and putting just one fish in there with some corals. is this tank too small for a blue spot jawfish or a hawkfish. i want both of them and neither can go in my dt now for various reasons. from what i'v read both fish are recommended for a 20g tank, but if its the only fish in there(i'm only going to get one or the other) would it be allright. my dt doesn't have a deep enough sand bed for the bsj and people told me the hawkfish would kill my clowns and pjs.
