i have a question? i have 2 common clownfish,1 stawberry dottyback,and a engeiner goby in my tank..so i bought 3 tiny yellow clown gobies and added them..(the guy at the lfs) said they would be alright to add..for a couple of days they have been getting nipped at by the sbdotty back..and once in a while by the clowns..iv'e also noticed the little clown gobies chacing and nipping at each other..so i woke up this morning and all 3 of them look like they have been beaten pretty bad..one is real bad..my question is ..who did this to them ?the dottyback? or maybe to each other? far as i know there is no hitchhikers in the tank..i have had this happen before in my 55g.tank and a few months later i found a huge hitchhiker crab..i just seem to have no luck with these little fish ..and i hope they make it..any answers greaty appreciated...thank you
