Hitchhiker cucumber id and behavior

[oool8899]

Found this cucumber on a paly colony, not sure what species but he reminds me of redfoots. He's firm like yellow cucumbers and has feet all over his body. I'm asking for id but also I moved him to a hitchiker safe tank and he started behaving strange expelling something. At first I thought it was his defense mechanism but it looks different than what I'm used to. It's these yellowish white dots coming out on strings he seems to be pushing it with his mouthparts.
