The pic below if of what I think is “Brittle “something” starfish. I have seen... lol... traces of him in my tank. ....I’ve seen small little “tentacles“ suddenly disappear under the rock... I’ve caught him twice. Once n my mag-glass cleaner. I was actually using him to clean my glass for a few seconds... he was pretty small... less than a 2” total diameter. He is now at least 7” in total diameter now... his primary body is the size of a dime.I found him in my sump tonight.

Just how big can this guy get? (That net is 3” wide...)
