They also like it when the light is not too bright. You can use floating plants or dim the lights to make them more comfortable. Make sure the tank has a good filter. This keeps the water clean and safe for them. Do a partial water change of about 25% every 1-2 weeks.

Tank Mates:
They are peaceful and do well with other friendly fish. Good tank mates include tetras, barbs, gouramis, and cory catfish. Stay away from big, predatory fish or very aggressive ones.

Breeding Harlequin Rasbora
Breeding harlequin rasboras can be a bit tough. But, with the right conditions, you can breed them successfully. It’s best to keep a young group of harlequin rasboras in a separate tank. This helps control the environment and cuts down on competition.
To set up the breeding tank right, keep the water temperature ideal. Harlequin rasboras need the water between 76-80°F (24-27°C) to breed. This temperature range encourages them to breed and helps eggs and fry develop well.
During breeding, female harlequin rasboras lay sticky eggs on leaves or in the tank. The male then fertilizes these eggs. Make sure there’s plenty of plants or spawning mops so females can lay their eggs safely. This also keeps the adult fish from eating the eggs.
After the eggs are fertilized, they hatch in about a day. The fry are tiny and need special food. Give them very small foods like infusoria or commercial fry food. Feeding them in small amounts frequently is crucial for their well-being and the water’s quality.
Right preparation and attention are vital for breeding harlequin rasboras successfully. The proper water, breeding spots, and fry food are crucial for success.
Follow these steps and you’ll find breeding harlequin rasboras rewarding. You’ll get to see the full life cycle of these amazing fish.

In an aquarium, it’s key to feed them well. A diet of quality flake or pellet food is good. Look for foods rich in proteins, fats, carbs, and vitamins.
Adding live food to their diet is beneficial. Offer treats like brine shrimp or bloodworms. These live foods are not only nutritious; they make feeding time fun.
Always watch how your fish react to new foods. Each fish might like different things. Make sure they’re eating enough by observing them closely.
