Is daphnia good for 2 1/2 week old fly? I heard they get sick after some time, I have been feeding brine shrimp and I don’t have any brine shrimp left to feed can I feed them daphnia? If sick what kind of sickness do they get and how do I treat them?
Yes, Daphnia is good for the fries.
Daphnia may carry bacteria and will cause the discus fry to get sick.
You can prevent or reduce it by:
Change water after feeding them daphnia.
Occasionally add salt to the tank.
Another method is to cultivate them inhouse by getting a daphnia starter culture.
