yay! i'm glad everything worked out for you! i once bought a hamster that turned out to be vicious and growled at me and bit me. i decided to return him. it was still sad. so i know how bad you must've felt having to give up your innocent non vicious bettas. you did the right thing trying to find a good home for them, but i'm glad they didn't end up in a filthy cup for the reast of their lives. you are a responsible pet owner for being willing to rehouse your bettas to give them a proper tank. oh and i would use the suction cups just to be safe.
