How do you breed scuds? I've been trying to recently but they've just all died except for a few, I have them in a tank with some snails and some moss, duckweed, and hornwort with a small HOB filter (came with the tank, it's a betta kit tank) and a sponge over the intake. I don't know what could be killing them off, but just about all of them have died. I've also heard you can collect them in the wild, how would one do that?
