Just discovered this hitchhiker in my tank - is he good or bad?

Theyre ok . Algae grazers i think i have some running around my rocks

Agree Stomatella! I have some....Do not try and pick them up. I was going to move some to refugium to eat algae there....didnt go well and I was being gentle! Just lifting with steady pressure waiting for it to let go of the rock, same as I do other snails. It ripped itself in half, and ran up my arm...leaving behind a fleshy wiggling chuck. Turns out it's a defense move they can do ...just like a lizard leaving a tail behind. 0o
