I have a 15gal hex tank with a few harlies and a couple cories in it. I've always wanted RCS but I don't want to set up another tank for just shrimp. Would shrimp babies be able to survive living amongst micro fish? I can put the cories in another tank if I have to. I just added some plants to the tank(had plant eating fish in it prior) so in no time the plants should be lush and full to provide cover. Any thoughts/suggestions?
