I have a Blue Ring as a hitchhiker on my LF. Found the guy last week after snails and hermits were being eaten. I know they are deadly and am willing to sell or trade to another hobbist who knows the proper care for this animal. I'm guessing he's been in the tank for a month now, after capture he's in his own lair (cup with holes punched)- he's in a dark cave where i understand they like it. I want to sell /trade him to more experienced people who keep cephs. *WARNING - this is a deadly animal and caution must be used. *Do not handle this animal with hands, bite can lead to DEATH. So with all that, GOOD LUCK!
