Im debating throwing some of my rosy barbs into an outdoor pond for the duration of the summer to give it some colour and in hopes that they'll multiply without my intervention for a change. I live in Canada so it gets cooler at night but it's rarely below 70. My other concern is that since it isnt my pond I can't count on the fish being fed every day although I think the person is fairly dilligent about such things I dont want to assume. Will the bugs etc be enough for them? We're just looking for things that can liven up the pond but that aren't goldfish.
