I just took the eggs out of their little place, poured as much of the water out as i could without pouring eggs out, and made a very dilluted solution, just barely had a green tint. When I poured out the water though, I noticed that some of the eggs were dyed blue, very blue. Will this hurt them any? What should I do now?

That is *not* the same as the Fungus Guard I have used in the past. It 
contains two strong antibiotics and a tanning agent. The color probably 
comes from the latter, potassium dichromate. One thing for sure, you are 
not likely to have any bad bacteria on those eggs! :-)

I have noticed that sometimes a few eggs will take the dye and the 
others will not. Those that were dark seem to have died, while the live 
eggs that go on to hatch did not get so deep blue. The anti-bacterial 
properties of the dye keep the eggs from spoiling so fast so fungus does 
not get much of any way to start.

I go along with the suggestions of others that changing clean water, 
often, in very shallow containers is more important than medicines.

That Java moss was a good suggestion, too. It usually has rotifers and 
paramecia that eat free-swimming bacteria and keep the water cleaner. 
They then provide some good, easy-to-catch first foods when the babies 
hatch.

>>Well, I just typed a bunch on asking if I could use Rid Ich from Kordon, but then I finally found where it lists the active ingredients, one being Formaldehyde. Well, I guess I'll do some more searching around and try and find something else, I'll first look for what you suggested.
