Bug on Trochus Snail

[actorfreak1791]

Would anyone know what this is and what I should do?? This is the second one I’ve noticed on my snails. The first one ended up on my tank and took it out, but now this is another one.

Really hard to tell what is on the shell with the blue lights on try and snap a picture when the white are on!!

Isopod perhaps? You might want to compare what you have to some pictures online and go from there.
