I visited a pet store that had some three giant, really depressed looking goldfish. Each were about 10" long, one either a black moor or maybe black bubble eye. Ithink the others are ryukin. They were crammed in a tiny, very shallow tank, in a dark corner, without enough space to move. They didn't swim, just sat there floating still. I wanted to free them, give them a good home, as I have tons of space, but they are charging more than $50 for each one! Any suggestions for how to negotiate "liberating" these sad fish?
