I got them food this morning before lights on. Problem is once lights come on they go running and hide. Same with anything moving towards them, theyre very skittish still.If you find they aren't getting enough food, you can target feed them with basters and syringes. Use something[food] meant for shrimp or something like BBS
I can happily culture green water for themYes Atyopsis shrimp can change their color, they can be anything from yellow to brown, green and even blue. They are still all wild caught AFAIK, that will tell you something about their care. You will have to add green water to keep them happy in the long run.
All filter feeders like clams, paddlefish and Atyopsis shrimp just aren't suited for home aquaria.
