And if you can't make a deal, suggest a cure for him. Clean water, aq salt treated water, medicated water. I do that too. I tell them all the time "oh this poor guy has a fungus growth, you should treat him with nice clean water with a bit of aq salt and extra stress coat for 4-5 days." lol either they hate me or tolerate me. Petsmart tolerates, Petco hates me (I've pointed out that their fish are clearly mislabeled to get more money out of them) along with my local wally world. Those people run when they see me in the fish section.
