However, setting up an aquarium for these little colorful creatures can be tricky, and that’s why we’re here to help! In this post, we’ll provide you with a comprehensive guide on how to care for the awesome harlequin rasbora, with a focus on the aquarium setup.

Let’s dive in with the various tips and requirements for this freshwater species!

Tank Size And Shape Requirements


The harlequin rasbora is a small species, usually measuring around 2 inches long. However, they need plenty of space to swim, and therefore, a tank of at least 10 gallons is recommended. The aquarium should be long rather than tall, as this best simulates the species’ natural habitat in slow-moving streams and rivers.

A rectangular tank is preferred as it offers more surface area, which increases the exchange of gases in the water.

Water Temperature And Chemistry


These rasboras prefer slightly acidic to neutral water with a ph between 6. 0-7. 5. The water temperature should be between 72–75°f, with 74°f being the ideal temperature for this species. Keeping the water parameters within the ideal range ensures the well-being and health of the harlequin rasbora.

Filtration


A high-quality filter is essential for maintaining the water quality and keeping the tank clean. Given that the harlequin rasbora is a smaller species, a gentle filter is recommended to prevent the fish from being sucked into the filter. A sponge filter is a preferred option since it offers excellent filtration without creating excessive currents.

Lighting


Even though rasboras do not require direct sunlight, providing them with sufficient light is necessary for simulating the natural environment. They prefer low to moderate lighting, and you can choose between led, fluorescent or incandescent lights. Ensure that the light is set on a timer for 8-12 hours each day, as this will establish a consistent light to dark cycle.

Plants And Decorations


The harlequin rasbora loves having plenty of hiding spaces, so it’s a good idea to add floating plants, underwater plants, and other decorations to the tank. Live plants like java moss, java fern, and amazon sword are great choices that offer hiding places and help maintain water quality.

Decorative rocks and caves also work well for these colorful species, providing ample places to explore and hide.

With these aquarium setup tips, you’ll be able to create an ideal environment for your harlequin rasbora to thrive. Don’t forget to provide them with a well-rounded diet, including flakes, pellets, and live food like mosquito larvae, to ensure their continued health and happiness.

Happy fish-keeping!
