There is no point in continuing the thread, you cannot keep shrimp with "George". He will eat the shrimp. I don't know how big he is now but he will go over a foot long. So if you must have him, get him tankmates that he won't munch on. Buy a small tank for shrimp.
Or buy feeder shrimp for him and realize they are his dinner and not your pets. There are several species of brackish water ghost shrimp that can tolerate a wide range of saltwater conditions.
Thank you. That's what I needed to know. In light of all the info I've gotten here, I think I'll hold off on pursuing shrimp until I can set up a seperate tank just for them.
