Fine!
That they become white after eating, I still didn’t notice … Perhaps mine do also….
I light the filter pot with a torch so they come busy to the light, as brine shrimps and I can catch them easily.
If they are older and the pot need to be resheduled, I see also dead ones swimming at the water surface. I think then we must be careful. I put the water through a nauplia sleeve and try to keep the living ones to put them back in the new water, but they write that you shouldn’t clean the pot.
Then it takes some days and good moina are swimming again at the water surface.
Nice little food! 🙂
