I culture both daphnia and scuds. But sometimes I can't feed them this everyday cause I have to let the culture recover. The other live food, which I buy, is live blackworms from the LFS. I usually buy about a tablespoon to 2 tablespoons every 3 weeks to a month. I keep them in the fridge and every 2 days I rinse them well. But I'd like to get another food in their diets cuase I don't want to depend on live food all the time. Sometimes my daphnia cultures crash and I gotta start over, and it could take time to get to a nice size before I can feed. I think I lost my daphnia culture outdoors. I am waiting to reseed in spring with the ones I got indoors.
But before that my indoor cultures crashed and I had to reseed with what I had outdoors. My scuds culture indoors has crashed once too.
