How to Breed Albino Corydoras

Set up a breeding tank for your albino corydoras. The tank should be about 20 gallons in size and should only be filled halfway with water.

Equip the breeding tank with a quality filter and submersible aquarium heater and decorate it sparsely with a few wide-leafed aquarium plants. Do not fill the bottom of the tank with gravel or other substrate.

Select a breeding trio of one male and two female albino corydoras and introduce them into the breeding tank. Because corydoras are difficult to sex it is imperative that you watch your cories for some time before breeding them to identify any natural pairings that occur in the tank.

Maintain the breeding tank at a temperature between 70 and 74 degrees Fahrenheit and allow your cories to settle in to their new tank for a few days. Feed the fish three or four times a day a variety of foods including flake food, pellet food, live and frozen foods. A varied diet will help to condition your corydoras for breeding.

Add a gallon or two of cool, dechlorinated water to the tank every night after the settling-in period of three to four days. Add enough water each time to lower the temperature in the tank by two or three degrees. Continue to add cool water to the tank every night until the tank reaches a temperature of 65 degrees Fahrenheit. The change is temperature is meant to simulate the fall of rain which occurs during the breeding season in the natural environment of corydoras.

Watch your corydoras for signs of spawning. During the mating process the male will fertilize the eggs and the female will pick them up and deposit them in various places around the tank.

Remove the adult fish from the breeding tank as soon as possible after spawning is complete. Treat the water in the tank with methylene blue, following the instructions on the bottle, to protect the eggs from fungus.

Bring the water temperature in the tank back up to 72 degrees Fahrenheit by siphoning out half the water in the tank and replacing it with a gallon or two of warmer water every six hours until the desired temperature is reached.

Maintain the temperature in the tank and substitute an air stone for the filter once the eggs have been deposited. After ten days or so the eggs should hatch. After the eggs hatch, replace the air stone with a sponge filter.

Feed the newly hatched corydoras live brine shrimp for about a week then slowly begin to incorporate into their diet other foods like daphnia, finely crushed flake food and microworms. Continue to monitor the temperature and change about five percent of the water weekly as the fry grow.
