Hi! I recently moved my Betta out of his 1.5 gallon and into the 20 gallon community tank and he's getting along well. Problem is, he seems to be eating/playing with the ghost shrimp I have in there. I was wanting to get some more colorful kinds of shrimp, but I'm scared to put them with the Betta. Would it be possible to have a small community of shrimp in a 1.5 gallon with a small plant or 2 and maybe a thin tower type decoration in the center of the tank(to serve as a sort of shrimp condo)? If so, which kind of shrimp(brighter than ghost shrimp) would be best for this sort of setup?
