D= that's terrible...
IDK I think the petco around here takes decent care of their Bettas (They always have pristine water) So I'm pretty sure they wouldn't be flushed.
Aggressive females now = craigslist. If I do a sorority of course...
Its required that they do that with any returned fish. (its to try to keep from their fish getting diseases.) When i worked at the petco in my area I was always the one who took the returned bettas and adopted them out if i was in on the days they were returned.
I also breed and often sell guppies, I have the following strains.
Double Dark Blue Moscows, Half Blacks, and Albino Blue Topaz.
If your interested in purchaseing a pair or trio just pm and i'll let you know what I currently have ready to sell. Or if you just want to see pictures pm me.
