Ok! I'm new to salt, but not new to the FW tanks. I been feeding black worms for some time now. it is very easy to keep them. you don't need to keep them cool. I know people will tell me im wrong but you keep reading how people care for them.
YES, you can keep them in the ice box, that don't last long. the reason you get the smell is that worms die everyday. that need to be clean everyday and you must use aged water (freshwater) not tap or ro/di. There is something in the tap and the ro/di water that kills them. I'm not sure but this was my project to stop letting 5# of worms die off so quick.
One day I went over to old fish keepers house and I saw how he was doing his worms. simple container with a airstone. I asked him you don't keep them cool, he asked me why? I said from what I read on the net everyone keeps them in the ice box. He said why would you do that they are fully aquatic.
So there you go, if you look up these wroms they live in ponds, the species name for these are Lumbriculus Variegatus. they are found all over.
However you guy should look into club buys, our local club buys from easter aquatics, others like myself go in with a guy he buys from Cal black worms.
My setup is easy 40 breeder full of aged water with three airstones. I keep 5lb every month.
Since I went to keeping my worms this way no water changes until the next ones come in and worms stay alive alot longer.
For some of you who can't keep this much try this(my brother trick) 5gal buck/airstone/ and a little sand at the bottom. He too had all the problems keeping them, from being frozen to dieing off overnight after this he sure made up for the loss.
one more thing you don't need anything in the tank, like bio ball or hiding places.
two main things air/aged water.
hope this will help.
