I began to see some instances of this too after looking harder. Any idea what species?Glad you enjoy!
I did add some asterinas already, same with some bristleworms. Currently I'm on the hunt for some green manjanos. Maybe some 'ugly' brown palys too lol.
They're a pretty common hitchhiker from what I read. Mostly from indopacific rock I think.
I wonder if you could keep some sort of flat worm or pest deemed sea slug? I know many are seen as a pest, although I also know many are unethical to keep. A shame really, they are so beautiful. I can’t say I know much on them though.
That is awesome to hear! How big have they gotten? Biggest I saw was about a month ago at a friends tank. It was about the size of a dime. I know that’s where they tend to max out, but let me know if you get any monsters!
