I have a CBS (Coral Banded Shrimp) in my 20 gallon, and have been having problems with Aiptasias, so I would like to add a Pepper Shrimp and also a Blood Red Fire Shrimp. I've read that CBS might kill other shrimp, but I've honestly never had any problems with it. Now, what really worries me is when the shrimp molt, as they will be weak and that would be the perfect time to attack.
