Eggs can be removed from the parents tank using a siphon or Python hose into a bucket if they are scattered. If they are attached, whatever they are attached to can be removed. Eggs on glass can be removed using a razor blade, fingernail, or credit card. If the parents were put in a spawning tank and then removed, then the eggs can stay in that tank. Eggs removed from their parents should be kept in a tank with appropriate pH, temperature, hardness, etc. with mild aeration.

Egg Fungus
To prevent egg fungus, a dilute solution of methylene blue can be added for about a day. The water should be a light to moderate blue. Unfertilized or injured eggs will take on the color of the die. If the die is not used, then those eggs that loose their transparency (often turn white) or appear "hairy" or "fluffy" should be removed. Loose bad eggs can be removed using a glass or plastic pipette while attached bad eggs can be removed using a finger nail or tweezers. If eggs are kept with the parents of some species including some cichlids and fathead minnows, the parent(s) will remove these unfertilized or injured eggs from the nest. If the fungus gets out of control (usually only when methylene blue is not used), all viable (usually clear with small eyes forming; some species like some cories may have colored eggs) eggs should be removed to a fresh setup with water of similar temperature, pH, etc. Newly hatched fry should be removed to separate quarters when egg fungus is present as well, as young fry can die from the egg fungus too. The eggs should be removed to a tank without any methylene blue prior to hatching. Fry do not take well to methylene blue. Usually, keeping the eggs for about one day in the methylene blue solution, removing the colored eggs, and then putting the eggs into a fresh tank where they can hatch without methylene blue works well.
