I know we do not have a ton of salt water keepers on here, but does anyone have experience keeping the anglerfish or frogfish (Histrio & Antennarius.) I guess my questions would be can they be kept with more of their own kind, are/is there anything else that is compatible with them? I am thinking of doing a saltwater algae tank with Halimeda sp, Caulerpa, etc. live rock, live sand and maybe a single mangrove tree (baby of course) and then a sump under the tank with chaeto (maybe some in the tank too). Does that sound like a good idea?
