im looking for a suitable fish for my 5.5g tank. so far im torn between a yasha goby and a tailspot blenny. i am open to other options though. i thought about a small clown but im not sure when my 25g would be ready and wouldn't want to leave him long term in a 5.5g. my only requirements are they are coral safe, i've heard stories of some "reef safe" fish munching on sps or other corals
