I been culling yesterday and today....I probably removed about 20-30 that had short gills (still have at least 100+ left, didn't even put a dent into the population :P)...not really sure what else to look for, but I remember seeing something about culling on the angelfish.net forums, so I will check there. They are eating a ton of flake now, heaing 100 snaps on the surface when they feed is pretty funny and exciting. I been hand feeding them some frozen BBS cubes, they love it. Every once in a while they will tap my finger thinking its food hehe.
I usually shut off the sponge and hang on filters during feeding as I dont want to waste the food, plus with the hang on circulation it gets messy all over the tank. No more have died since the mysterious deaths which I'm pretty sure was due to a bad batch of BBS.
Rebel, its natural that some eggs will turn white, if you want to check to see if your eggs are fertile just pull them once you see that they have finished, and are fanning the eggs. If they are new parents, it will take them anywhere from 2 to 5 days (or in some cases never) before they will get the hang of it. If you see that the eggs turn white after just 2-3 hours then maybe they are doing something wrong. If you see that they are slowly turning white over time, its most likely just fungus, which either means that your water quality is bad, and or your parents arent eating the white eggs preventing fungus from spreading to other eggs nearby. Either way, one sure way to check is to pull the eggs, throw them in a 5-10 gallon tank, use an air stone or just the tube and stick it near the eggs, add some anti-fungi and wait 48 hours and check for wigglers (hard to see, you really have to look close).
What kind of tank setup are your Angels in? Are they in a breeder tank or community?
Thanks for the replys
