If it is a stomatella, don't get rid of it. Good algae grazer.
Thank you both I'll be working on ridding the pests this week and next. Don't want to do too much at once and upset the balance in the tank. There are waaaay too many bristleworms for my liking as well so that will also be delt with. I don't mind some as they can be beneficial but too many can also be a problem.
