I finally got some crytstal red shrimp and have lovingly kept them all together in a large suspended net in one of my tanks just until their numbers increase. Don'tworry they have timber in the net as well as live plants, even some rocks to wonder over. Only trouble is the crystal reds have discovered a way out of the net while the resident cherry shrimp have found their way into the net. Try as I might I can't find where the change over is taking place, but I would really like the two types to stick to their own areas.
