I recently had both cleaner shrimp die with in about a week and a half of each other the water parameters are fine. they where both fairly large and looked fully grown. is it posable that they could have been old? or is it possible that my chocolate chip star took them out? the only thing I've done differently is started adding Kent's calcium to the water, I know that calcium is good for them but if there was to much could it hurt them?:shake:
