Corydoras are such beautiful fish, and there are so many species to choose from. And except for the pygmies and the long noses, their personality and care facts are reasonably consistent except for their temperature tolerance.
So today. Instead of repeating a lot of what I’ve already written about when I spotlighted some other cory species, I want to address a question that I used to struggle with.
Pink Corydoras: How do you get cory eggs off the glass without breaking them?
Most of us keep corydoras in community tanks and the eggs the periodically lay after water changes do not stand much chance of survival among the residents of the aquarium. As a kid, I read many books about fishkeeping, and all of them recommended using a razor blade or sharp knife to remove the eggs.
However, in practice, that never worked well for me. The few times I tried I broke most of the eggs. It wasn’t until much later that I learned about rolling the eggs with your fingertip.
Rinse your hands first to remove any oils, hand creams, sanitizers or soap from them. In one hand hold a paper cup under egg you have chosen.
Place the tip of your index finger on the egg and gently move it back and forth until the egg detaches from the glass. You can then let it fall into the cup.
Once you have all the eggs that you want to collect, put them in the hatching tank where you can raise the fry in safety.
Cory eggs are susceptible to fungus, so if you want a larger batch of hatchlings, you should use a fungicide.
Anyway, back to the pink cory. Like all cories, it prefers to live in groups, but unlike others, their group can be smaller. Four individuals are enough to keep them happy. A group of four can comfortably live in a 20 gallon/ 80-liter tank.
Size: 4-5cm/ less than 2″
Temperature: 22-26°C/ 72-80°F
Feeding: Easy. They will eat all types of food.
For all cories, sand or rounded gravel is best, so their barbels are not damaged. The also like to have at least one clump of plants that they can shelter under. They also need access to the surface of the water to breathe. The pink cory does best in water with a pH between 5.0 and 7.0.
Eggs are attached to the solid objects, often the side of the glass. When spawning, it is best to use two males per female.
