Angelfish fungus??

[ExPeNsIvE HoBbY]

Ok, so I have 4 pairs of angelfish that have been spawning for a while now, but it seems like the last 3 batches of eggs have gotten quite a bit of fungus. I am having a hard time figuring out why all of the sudden this has become a problem. I artificially incubate them in a 10 gal half filled and treated with methaline blue. I keel the temperature the same as the breeder tank, and use water from that tank to fill the incubation tank. I also cover the tank with no lights on for the first 4 days.

Any ideas as to why this fungus problem is occurring? I feed the parents a special breeding formula of earthworm flake and also brine shrimp.

Thanks for any feedback

good water flow under/around the eggs?

that's why the parents will 'fan' the eggs.

also could there be a fertilization issue? unfertilized eggs will turn white and fungus over pretty quick

There is a bubble stone setup directly underneath the eggs which are propped up at a 45° angle to cascade air across the eggs. The eggs should be fertilized as the parents are being fed foods specifically designed to condition them for breeding.

methylene blue usually works pretty good at fighting fungus.

even tho you are conditioning the fish doesn't always mean they are at their peak.
sometimes the males may be less 'potent' depending on demand and age(very true with young angels)
how old are the fish? I had a pair that were usually pretty good at fertile eggs..then they just dropped off..best bet would have been to remove the male and give him time to recoup...I decided I didn't have time to continue.. so I let them slide
