Christina,
Let me see if I can mediate this.
For instance, I have a couple of Harlequin Shrimp. They eat only starfish. When someone is getting rid of a chocolate chip star - and virtually no one wants them because they aren't reef safe - I try and feel them out about how they feel about their pet. Sometimes, people are put off by this...
Now, sometimes people aren't too tactful about it. There are people who keep goldfish as pets, those that buy goldfish for their Oscars, and those that buy them to eat. Our wet pets live by eating other animals.
Your chromis weren't selling - heck I have one that I've tried to remove with a tiny fishhook. MOST people hate their damsels after a while - they are mean, they eat lots of food, and are in general pests. They bite too. In his defense, he has no idea whether you really liked the fish, or hated them. If you were turned off by Mike's offer, just politely decline.
Finally, don't let the actions of one member run you away. Not picking on Mike, but all it takes is $25 to become a Charter Member.
