From what I gather, they got the tank from his family's business and the clowns from Petco. Petco is safe this time lol though they should have asked.
I remember buying clowns for my 5 gallon when I started lol had to get my story straight before I went to big al's. (My local LFS advised me on how to pull the caper off.) Oh ya I said, they are going in a 20 (litre) Almost blew my cover when I asked for live rock rubble instead of live rock.
Times have changed, several fish have gone back do incompatibility with tank mates,(Clowns are not community fish) I have bigger single-species tanks now, just saying sometimes we are the villain. I still get a little nervous when I go in there in the older Asian fella peers over his glasses recalling the thousands of customers hes seen in the last few years. Once I get the subtle nod I know its OK to to proceed lolololol.
The older staff is really good for asking questions, though maybe some of the younger people don't, maybe they can kinda tell if you have a tank or not.
