  Since you have the luxury of 3 different egg clusters, you can try moving one cluster to a seperate tank with a sponge filter. Chances are not all the eggs will hatch. As far as the other 2 clusters, I would top off the tank and make sure the eggs are always submerged in water.

  Clown loaches lay eggs. The only way to maximize survival rate would be to seperate the mother from other fish in the tank. The eggs will not survive predation once they are hatched.

  The females are not normally this tempermental. You have the rare female that is.

• Our parrot fish have laid eggs. Some have turned white. How long does it take for the eggs to hatch and what should we do in the interim?
  
  You'll need to remove the white eggs which are fungus infected before it spreads to the other eggs. A turkey baster is good for this job. The eggs should hatch in about 3 days.

  When livebearers give birth and the fry are seperated from the community fish (via a breeder net, or seperate fishtank) a good rule of thumb for when it is safe to add the fry back to the tank is when they are approx. 1/4 the size of the adult fish.
