I have a couple goldfish I bought for DS for a bit of fun.
I now regret this as my tank isn't very big and the fish constantly come up to the surface to gulp air !
I change their water quite a lot, but the water gets dirty very quickly.
I feel very cruel, but I don't really have room for a big fish tank.
Can someone tell if the fish would survive if I let them loose in nature ? Where ?
Alternatively would a pet shop take them back ?
Thanks !
