Thanks for answering. I asked because I had an interesting situation. I also have a Gramma who of course if very docile and wanted another for one of my other tanks. My LFS, I had been there a couple times last week and saw one and couldn't bring him home right away because my qt already has someone in it right now. I paid for him and they put him on hold for me. I was in the other day and told them I'd be by yesterday and they had him one a tank with info about him being sold etc. I was tied up a friend ran down to pick him up for me but when I got him home, he's not the fish I had previously seen, it was clearly the dottyback and knowing they are aggressive, I was just curious. The LFS regocnized the error and gave me a gramma also but I haven't picked him up yet. No need to return the dottyback because I have an open tank so I can start an aggressive one but was just curious your thoughts. Thank again
