    Hey guys, I'm new to planted tanks and am working on getting a low-tech 29 gallon established. I am interested in establishing at the least a population of Daphnia but also potentially other copepods, rotifers, hydra etc. But from what I can glean from the forums, these are things people are generally trying to get rid of in their tanks. Any suggestions on establishing a more robust micro ecosystem in the tank but avoiding potential problems?

    I do intend to have fry and shrimp in the tank but will have separate breeding facilities so as long as adult Neocaridina (i've never kept them but want to) aren't harmed, I don't mind if the populations are kept in check in the main tank.

    I've also been pondering a refugium tank delivery system for select critters. I would also like to add a bivalve bed eventually. Any/all advice or insight from your experience is welcome, thanks!

    Don’t tell me you want hydra. It’s a dangerous pest to fry and shrimplets everyone try to avoid.. Daphnia, copepods and rotifers are fish food hobbyist cultivate to feed fry, but never for ornamental purpose.

    I cultivate daphnia in outdoor tubs, rather easy, just provide sunlight and nutrients. I introduced a small potion of daphnia in my shrimp bowl, and it comes with other critters you mentioned. With fish, daphnia will be eaten quickly. They survived a long time in my shrimp only bowl and eventually vanished. I don’t think shrimp eat daphnia or any live critters. But without green water algae in indoor water, daphnia is slowly starved to death.
