What is this slug looking thing?

[Skay]

My green star polyps weren’t opening for a few days so i take it out and find this thing right on top of the frag. I gave it a dip and it fell off. What is this thing?

Assuming it has two little horn looking things on its head, I’m inclined to think it’s a Dermatobranchus sp. nudibranch- if so, that could definitely explain your unhappy star polyps, as they eat octocorals (soft corals, gorgonians, GSP, etc.).

If you have a coral eating nudibranch in it, then yeah, I’d assume you have an infestation just to be safe. I’d check for eggs on all soft corals, but particularly the GSP (GSP seems to be what these typically come in on, and since it’s what you found it on, it seems like a good place to start looking).

If you haven’t added anything in months, then I’d guess it’s been hiding out and feeding on something the whole time (possibly growing too).
