Tips for Playback
The first step we will do is to lower the pH values to 6.5 and maintain a temperature of 25 degrees in the aquarium where we will put our penguin tetra fish to reproduce.
These fish need little light to spawn. We will proceed to cover all with cardboard or other material, leaving only the upper part uncovered.
Luckily, penguintetra fish will not eat the eggs once they are laid, so there is no need for a rack. Once we release the couple inside the aquarium where we will have the young, both will need a few days to adapt to the new habitat.
After these days, the laying of eggs will take place during the afternoon and very close to the surface. The male will try to conquer the female until it spawns. Once the eggs have been released, we will remove the parents from the aquarium and remove a large part of the water.
The young of the penguintetra fish are born.
After 12 hours, the first larvae will hatch and stay in the darkest places in the water tank. In the bottom of the aquarium, the eggs that have not been fertilized will remain. They must be extracted through a fine tube.
From the fourth day after the penguin tetra fish have been born, the fry will be able to swim freely. From now on, we will begin to give it a little light by removing some cardboard or the material that we have used to cover the aquarium. We will also begin to feed them paramecia on a constant basis, to prevent them from starving.
When three weeks have passed since the fry began to hatch, we should move them to a larger place. We will also begin to change the food for brine shrimp nauplii, and finally, we will proceed to uncover the aquarium so that it receives natural light and they get used to their new life.
