Can anyone please tell me what this thing is in my tank. Its about 1 inch long pure black, slug. Its completely black and has 2 eye stalks and what looks like 2 little black puffs near its end. Right at the end of the eye stalks are what looks like 2 white dots for eyes. Please tell me if this is harmful or not for my reef tank..
Thanks
