It was in my refugium, on the glass , Sluglike ; ondulating foot, with curled antenas and an inside shell skeleton it would seem and a long mantel as a tail.
i randomly found one of those in my refuge... but he was a quick mover and i can't imagine him being harmful so never messed with him. he's a lil smaller than yours by the looks of the pics
+1 on stomatella. They are great as cleanup crew. My frag tank is full of them. You will see them stand up and release small clouds of sperm & eggs to multiply.
They were wiped out from my display. Thinking it was due to my peppermint shrimp.
Thanks guys much appreciated. Yes i've red about it so i've returned it ti its home
Thats the fuge; it feeds my main 150 Reef tank by gravity thats why its so high, i have 25 species of macro algaes and seahorses on one side. I knew i couldn't hide the flex pipes so i made a them out of it. I turned the room into a Borg room , green lights and all lol. I like the mad scientist look.
