I had nudibranchs like a year ago for my other tank in order to cleaning up aiptasia, as soon as I dropped those guys into water, never got a chance to see them again.
Today, in my small tank, I spot this little guys crawling on the glass, it does look like a nudibranch but I am not quite sure.
Anyone can help?
