Here's a link on Rosies
Check out Robyn's Rosy Reds at http://www.fishpondinfo.com/rosies.htm
She gives you all the info you need on raising them in a pond or aquarium. We tried putting some leftovers in a new aquarium and promptly killed them. Now that it's aged, I might try again.
The couple of times we've tried thme for bait, we didn't see any difference in catch rate, but we also have trouble finding them large enough to use for bait since we have to buy them at an aquarium store. They sell for them for feeder fish and want them really tiny. - Roberta
