My friend has some ghost shrimp in her tank and she was telling me how clean they keep the tank. I was thinking about getting some, but am afraid that my fish will eat them. I have 1 pleco, 1 lace catfish, 2 pictus catfish, 2 kissing fish, 2 three-spot gourmanis, 1 dwarf gourmani, and four mixed fruit tetras. I am not going to get the shrimp right away because I will be getting an 80 gallon tank soon. Are shrimp a good addition?
