i bought a bristle nose pleco about a week ago, and he is so cute. but it could just be my paranoia but i wonder if he is ok or not. he moves very little, i know that they are nocternal and all, but he has not ever attached to the glass. all he does is sit in a spot until something else come too close then he moves to another place. I dont know if he is scared or too big is about 3 1/2 inches and a little chubby but i thought he would be a little more active. :dance
