Breeding Green Eye Rasboras can be hard since not much is known about how they breed. They are thought to scatter their eggs and spawn regularly.

To raise your chances of breeding them, set up a special tank. This tank needs dim light for the right breeding mood. It also needs a special bottom so eggs can drop through without being eaten.

It’s key to get the adult fish ready together. By feeding them well and adding cooler water, you mimic their natural spawning triggers. The temperature is very important for the eggs, which hatch in 18 to 48 hours.

After the eggs hatch, the tiny fish need good food to grow. Feed them things like Paramecium or infusoria. This helps them during their early life.

Tips for Breeding Green Eye Rasboras:

  • Set up a separate breeding tank with dim lighting.

  • Monitor temperature as it affects the incubation period of the eggs.
  • Provide appropriate fry food like Paramecium or infusoria for the young rasboras.

By using these tips and creating the right conditions, you have a better chance at successfully breeding. Then, you can watch the baby Green Eye Rasbora fish grow in your tank.
