well spent the weekend at the girlfriends. left Saturday morning and all my fish looked fine and healthy. got home tonight and my male mangano lab hybrid was dead. he had been eating fine and was the king of the tank. he took the throne from his daddy in the tank. he was a really thick and healthy cichlid. not sure what happened. he shows no signs of being picked on either. fins and tail in perfect shape and no scales missing. Just one of those odd things i guess.
