I tried getting pics, but they are so small it looks like tiny red dots. I just recently noticed them. They are around 1/16" maybe 3/32" long, and are solid red. They look like the typical nudi/slug, but they don't have the frilly patch on they're rear end. I have seen at least 20+ of these things on liverock and floating in the water column. Any help would be greatly appreciated, and thanks for looking.
