I know that zebra danio eggs are supposed to hatch within 1-5 days. This is my second time trying to breed danios. The first time I could see the tiny fish in the eggs after 10 days or so but then 3 days later they hadn't progressed so I tossed them. The first batch where in a tank with a filter (with panty hose over inlet), a bubbler, and red cherry shrimp. This time I put some methylene blue in the water right after I moved the eggs. They are in a container with no filter or bubbler. This is what they look like after a week, and what the previous batch looked like after a week before they progressed and looked like curled up fish in the eggs: Is there still a chance they could hatch? They are still clear and have a small yolk/white dot on the inside. My water is approximately 70 degrees F, and we have hard water. The eggs have been in pretty fresh water.
