hello! i had a bicolor blenny and a royal gramma at the same time a while ago...and they did great together and did not look anything alike! the blenny was very personable and interesting; his name as wally. the gramma liked the caves and was pretty, but not out and about much. both succumbed to the ich epodemic (sp?) from the pet store several months back though.. they look totally different; different shapes, personalities, and colors. the only thing similar is that they are fish, have eyes, and are half one color and half another, hehe. clearly i am in the minority here though! bicolour blennys are known to nip at corals though. i cant wait for your new frag pics!!!!!
