Hi everyone, New to thread. Aquaponic grower living in Madison. I'm looking for a creature that I could add to my grow beds (essentially an aquarium with plant roots hanging down into it) that could clean out some of the solid fish waste but wouldn't eat plant roots. I've tried to culture Scuds without luck. Heard cherry reds would be good but need to find an inexpensive source. Is there anything else you can think of?
