Will adding daphnia improve water quality? When they reproduce, the added mass of the colony has to come from somewhere- I'm wondering if they filter your water to some degree?
I'm not thinking of adding greenwater or any food to the tank though- it's my shrimp tank. But I thought I might grow daphnia for the purpose of further stabilizing my ecosystem. And to raise food for other fish.
Would daphnia die off if you don't feed them? Or will they survive on algae and stuff in the water? I have a 55 gallon planted tank, btw.
