My fish (especially my cory cats) love live bloodworms. I can only get them at one store locally, but the owner is moving the shop and he'll be down for 2-3 months. I bought a pound of live bloodworms and I'm keeping them in perforated-top containers in the fridge. I've had no problem keeping smaller quantities this way for a week or so, but to keep these alive for a couple months I'm guessing they'll need to be fed. Any idea what they eat?
