Hi im new to this web site and i was wondering if i could get some feed back about my new fish, a bicolor blenny? I have a 10 gal with a percula, 2 red leg crabs, feather duster, and a realtiveley small colony of yellow poloyps. I just added the blenny about a week ago in hopes of helping to control my algea a little, but i really havn't seen him do much of anything. I now they are supposed to be laid back, but i have only seen him out of his spot once, and i have never seen him it. Although he doesn't seem to look stressed out im still concerened if this is normal or should i be a little worried?
