I put methylene blue to because white fungus killed the ones that hatched, the fungus made the shell give out. The remaining eggs are all good, but one seems white, it may hatch or it may be fungus, I will know tomorrow. I put the vase in my 30 gal clown tank to keep it warm, but does any body have ideas or recomendations? This is the first time I am just not able to get fish to cooperate or eggs to live even though they have eyes and hatch. They get nice parent water 4 times a day an air stone, meth blue, I just have only one hatched with a yolk sac and 5 eggs left, one looking a tad withish, is it hatching or infected? don't know.
