I'm half tempted to get another moray, maybe competition will spur his appetite... I don't have room for that right now tho.
I'm going to do another large tomorrow and see if that helps anything. Parameters have been spot on. It's not copper or metals in this tank, the shrimp and snails have been fine the whole time.
If all else fails, next week my QT will be empty. I'll move him over there and start treating with metroplex and kanaplex in the water for internal parasites. I've tried two doses of prazipro in tank with no results.
