Q's about eggs!

[Ooulophilia]

Kathy55g was mentioning that fungus is the #1 prob with eggs, and I just lost the bulk of a maroon clutch to fungus, so...

From my freshwater breeding days, I would always add a dose of malachite or formalin to the tank after the eggs had been laid to prevent fungal infections. Would this be applicable in SW, or has anyone tried any preventitive measures like this?

IMO the best way to prevent fungus is to keep the eggs with daddy fish. He will keep the fungus off of them better than anything. I would not medicate the broodstock tank. If you are pulling the eggs early, you can treat the eggs briefly outside of the aquarium in a small volume of water, but I am inexperienced with this method. Perhaps someone else will chime in.

We used to put in about 0.5 ml of formalin in the seabass hatchery I was at. That was in 5 gal buckets with millions of eggs and we left it for about an hour before we dumped them into the incubator tanks.

I believe salmon farmers use iodine to clean up the eggs too but you would have to look into that one for sure.
