Ive just noticed these little bastards floating around. I havent moved my shoal into my 120 gallon yet, its not even filled or setup yet. I was thinking if I completely drained the tank. Put my fish in the bigger tank. Then, let the tank with the worms just sit there for a day or two empty. There should be little or no water in the tank, probably just gravel. Will they die off, or survive? What do you guys think? I'll let ya know what happens in the next few days. Just curious if anyones tried something like that. I've read post saying they've either used meds or just thorough, repeated cleanings and removing leftover food. Thanx
