After adding two Lettuce Nudibrachs into my aquarium to deal with a Bryopsis Algae issue a day or so later I stumbled across this guy moving on the glass. Not sure but to me it looks like a baby Lettuce Nudibranch. Any thoughts?
I have no idea. What's it been doing since then? Have you seen it since?
Well a member on a another forum had the exact some thing in his aquarium. They are Arminid Nudibranchs. I discovered the source of where they were coming from in my aquarium when I was told that they feed on Soft Coral. I had purchased a Clover Colony that my wife thought was pretty and even though my water parameters were correct it just was wasting away. A few days ago after finding out what these guys were I removed the entire colony and rock since it was covered with them. I haven't seen any stragglers in the aquarium since.
