When my discus fry is about two or three weeks old, every day a few of them die until there is nothing left. What could be the problem because this happens every time and i have lost a lot of fry this way.
What do you feed the fries? When they are two to three weeks old, you will feed them brine shrimps or daphnia. These are the baby food. Have you checked the water quality? Is the water clean? Have you changed water? Do you apply Methylene Blue to stop fungus growth?
