It honestly shouldn't be a problem. First off, the likelyhood of that many offrpring living to adulthood is pretty slim. Secondly if there are any fish in the tank they are most likely going to find the young ones pretty tasty.I am planning on having 6 Cherry shrimp in my 29 gallon aquarium. But, I read that these little guys reproduce rapidly. I know their small, but gupply-sized broods will overrun my tank. Thoughts?
