Hey guys. I have a 50 gallon tank I love the inverts. Starfish shrimp, snails, crabs. Can you over do it with inverts. I have two peppermint shrimp that come out at night. I want to get a cleaner shrimp also would love a fire shrimp to give a splash of red. I figure more cuc would balance it self since they are cleaning everything up. Any thoughts?
