iam thinking of plumming a small seahorse tank(24g hoodless nanocube) to my 75g FOWLR, i would put a T in the return line to go to the NC and drill a hole in the back of it so the water gos threw back to the sump so it would all be one big tank and less maintence then two seperate ones, but the SH need 74 and iam not sure if my other fish would be ok at that temp, other fish would be V lion, niger trigger, red coris wrasse and possibely one of the following SF eel, zebra eel, YT, foxface, DF puffer will any of these fish have prblems with lower temp or is there anything iam missing?
