I don't know if its possible to know but could anyone tell me whether this Nudibranch is bad or not. I just noticed when I got home today.
Oh we'll I'm not taking any chances, seeing as how he strangely resembled the color of my zoas. You can't tell it by the pic but he was bright green on his back.
It looks like an aeloid nudi. They do eat zoas. Check this link for the picture of what the eggs look like. Hopefully it didn't lay any. http://newagereefs.com/forum/54-reefnotes/7124-zoanthid-eating-nudibranchs-beautiful-killers
