For three years, I bred them and sold them to my LFS in Iowa. They were kept in a 10 gallon species tank then. When I moved to Texas, I only kept 5 female and 3 males (the females were all berried). Since April, they have lived in a 40gallon breeder planted tank. I don't know how many are left, but I know there are 3 berried females that I put back when I took the rest to the LFS. I'd guess there are 4 or 5 other sub-adults and some juvies hiding in the plants. I had thought the fish would keep their numbers more in check, but they are breeding outa control! They talked me out of my 'black' red cherry shrimp female too. She had dropped her latest brood, so I'm sure some of her offspring are hiding in the plants.
