i got a vulgaris today that is going into my 75 gal .... when i was doing the drip acclimation, i looked up at my tank and noticed little 1/8-1/4 inch long white slug looking things moving around on the glass that had NEVER been therebefore.... i also noticed thousands of little tiny tiny whitish clear critters on the glass also.... i wasnt sure if my octo would be safe in the tank with these things? what should i do?
