Hi, I've had a true plague of these snails for 10 years, however, I only view them as a pest because it's hard to tell if they're dead. I've had no egg problems breeding apistos in with them. I always leave a light on for the mother apisto though. -Gary ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
