I have a 55 gal tank with about 53 pounds of live rock and 1 scooter blenny in there. I bought him when he was a little skinny and didnt look too healthy (bad idea). Anyways I bought some DT's copepods about a month ago and scooter is still in there and he is almost fat at this point. He is alot more active and visibly plumper than when i got him. My question is that my LFS has one of the really cool looking red scooter blennies. Would my tank support another scooter? Would there be any aggression between the two of them? I can always buy more DT's but if my tank wont support it without constant additions of pods then is it worth it? thanks..
