We have to mince their food, as they cannot eat normal size fish food flakes. However, even smashing food in a bowl with the end of a wooden spoon still produces flakes that are too big for them to eat. The size of a grain of salt is too big. I am work on trying to get a fine powder-like size, but that is a lot harder than you think.
I have tried several times to get a good picture of them, but it seems almost impossible. Here are two attempts, in which you can see little blur spots, which are the baby fish. I think there are 10 babies in the above picture.
