Would it be OK to keep a small group (say 2 - 3) Antennarius maculatus in a FOWLER 75 with a 75 overflow? I have all the equipment I need to set up this system and plan on setting the system up to cycle within the next week or two. I would also like this tank to have coral some time in the future. Obviously I will not be able to keep shrimp in a system with Antennarius maculatus But, I assume I can still keep hermit crabs, snails, and a single star right? Any help is greatly appreciated! Thanks 
P.S. I have seen a variety of care sheets for this species and tank sizes range form min of 20 gal to 70 gal......... Do they need 20 or 70.... Please help LOL!
