Default Copepods and Daphnia

I collected inverts from a local water source using a bottle trap, I managed to get both a copepod sp. and I'm pretty sure I got some daphnia as well (murky water hard to tell). reading online I saw a few people mention that copepods will eat young daphnia and even fry but no academic sources seem to back this up. I was wondering if anyone on here has had any experience with this.

I culture daphnia in two buckets outside. Other creatures have cropped up, including ostracods. The cultures are running just fine. I honestly haven't looked close enough to determine whether there are copepods in them, but I'm guessing there must be.

If you're concerned, raise some daphnia alone and then raise a mixed batch. There's no better way to learn than through personal hands-on experience.

Do you plan to raise them indoors? I know a lot of people do that with success, but I tried and found it to be more work and effort than I wanted to deal with. It is surprisingly easy to raise them outdoors, although I obviously have no access to them through the winter. Their numbers will explode and crash in cycles through the summer, but you'll always have enough if you run more than one culture at a time.

Good luck.

I've got an outdoor tank and an indoor tank, I was originally planning to keep them separate but I couldn't see the copepods until they were already in the tank. Thanks for the input!
