I've had a small out break of aptasia over the last few weeks, I thought I eradicated them from a few frags I had before moving tanks in December. It hasn't been too bad maybe two dozen total but then I noticed some small ones popping up in nooks of my rock. Yesterday I grabbed 5 peppermint shrimp from Optimum. They vanished pretty quickly since me melanurus was being very interested in them. Well I hate to count my chickens before they hatch but quite a few of the largest aptasia are completely gone and a lot of smaller ones I've been noticing are too. Hopefully they will continue to snack on the aptasia before my melanurus snacks on them.
