Harlequin Rasbora

Harlequin Rasbora is the most sought-after fish because of its beautiful metallic appearance and ease of maintenance. 

A massive school of Harlequin Rasboras fills the upper regions of the aquarium with movement and color so vivid that even non-hobbyists are impressed.

The Harlequin Rasbora is easily distinguished by its distinctive black “pork chop” shaped patch. Males will have lovely shiny copper/orange bodies, but females will be more golden in color.

The distinctive triangular patch starts near the dorsal fin and ends near the base of the caudal fin. The female Harlequin Rasbora’s patch is somewhat rounded at the bottom with an extended tip.

The patch on the male Harlequin Rasbora, on the other hand, is straight. Female Harlequin Rasboras are also larger than males. As they grow older, juveniles will darken.

The Harlequin Rasbora thrives in a well-established planted aquarium with open swimming spaces. The Harlequin Rasbora should be kept in groups of 8-10 and kept with other small, docile fish.

The Harlequin Rasbora’s kind disposition makes it an excellent community fish.

Rasbora heteromorpha spawns primarily on the undersides of broad-leaved plants. A breeding tank should be set up with shallow, warm, acidic, soft water and broad-leaved plants. Pair a young (9-12 months old) female Harlequin Rasbora with a two-year-old male to induce spawning and provide live food items.

Remove the parents after spawning and keep the aquarium dark until the eggs hatch (after about 24 hours). Feed the infusoria fry.

II. You would love the fish because…

The Harlequin Rasbora’s look is where these fish stand out. The species takes on the shape of a diamond. They are much wider in the middle of the body. The back end and head taper to a smaller point. The tail, in particular, has a more pronounced taper to emphasize the tail.

The fish has a light pink or orange coloration. The exact hues differ from one instance to the next. Not only that, but the colors can vary depending on the water.

The color covers the majority of the body. This includes the skull. It’s largely concentrated on the tops of their bodies. The bellies are usually bright white.

The hue isn’t limited to the body. It is commonly observed on some fins as well. The dorsal and caudal fins of several specimens are darker than the rest of the body. It shines out against their scales’ more muted tones.

III. Is this fish species peaceful or hostile?

This fish is peaceful and enjoys swimming with members of its kind and other species.

IV. Species compatibility

Cardinal Tetras, Bettas, Neon Tetras, Small Barbs, Dwarf Gouramis, Danios, other small Rasboras, and Cory Catfish.

V. How to feed this species?

Rasboras are not picky eaters and prefer a varied diet of high-quality flakes or granules as well as live items like daphnia and artemia. This food can be supplemented with meaty options like freeze-dried bloodworms or tubifex worms. Rasbora also enjoys fresh veggies regularly.
