Does anyone have any tips on limiting fungus in eggs? Would it be possible to use any of the same methods that are effective for adult newts, or do I just have to hope for the best?

If you read the first part, it suggests using salt baths for eggs (I personally do not recommend salt baths):

Frequent water changes and keeping it at cool (60F) temperatures seems to help slow the invasion. If your eggs are near hatching, they might hatch in time to escape the fungus.

It's also best to separate the eggs with visible fungus from the non-fungus covered eggs.

Other than that, yup, hope for the best. http://www.caudata.org/forum/clipart/happy.gif

There is some sort of blue-colored fish anti-fungal that has been used successfully to keep fungus off eggs. I can't remember the name.

As I recall from our chat, you are raising crested newt eggs. Half of them are genetic duds and will naturally develop fungus. I have never had a problem with this fungus spreading to the good eggs. But if this is the problem, try removing the duds as soon as they are identifiable (by lack of development or by early signs of milky color or fungus).

Saprilagenous fungal infections are more effective at cooler temperatures however the temps needed to inhibit the fungus would not be appropriate for newt eggs.
In general, I just remove the infected eggs if they appear to passing the infection on to healthy eggs.
