while cleaning my hatching tank today I noticed a large amount of small white worms clinging to the glass, from what I've researched I think it could be planarian worms but im obviously not an expert so I cant be sure. my fry have only been in the tank for five days now so most of them are still in wriggler stage and im worried that these worms could do them some harm or even kill them, does anyone have any advice on what to do or how to get rid of them??
