i was thinking about adding a group of cherry shrimp into my 20 gallon with my 2 mollies and a brochis. The tank is moderately planted with numerous caves and other hiding spots. I know they will breed and that will mean some,if not all, of the baby shrimp will get eaten(but if one or two live everytime they breed i would be happy) I was just wondering if the adult sized shrimp willl be safe from the other fish?
