Ermmmm i think they might, but i guess the main moral is that we should all be more thoughtful of the fish we buy. Even I've made a few mistakes, so yeah. Just call around
My LFS will take healthy fish but they will only give you store credit for them. Which is just fine with me. I am really lucky....they will also take your sick fish and put them in a hospital tank and treat them for you. I love that place and they are so great.
I would call around to the stores in your area and ask. Yes, it's done.
Since some places will give you store credits, etc. I would call around to find one of those. Depending on what you have, it might be worth the drive if you find a place
I think it depends on what you are trying to get rid of.. Common guppies, platies, swordtails.. probably not, 100 other people try the same thing.
Now if you had rarer fish, then yes. Rare live bearers, bettas or even some cichlids, such as rams/dwarf cichlids, many shops may pick them out, unless they are too odd for the casual buyer.
most of the time yes, but a lot of stores only give you credit. also, dont expect to much for the fish, as tricksterpup said. my LFS was only willing to give me 12 cents for the swordtails that i raise :sad: (oh well, i wasnt expecting much)
