One of the most popular of the Rasboras is the Harlequin Rasbora. They sport a striking blend of red colored fins and a red toned body that has a golden shine to it. They also have a black triangular wedge in the middle of their body. The coloration of the fish makes it an attractive addition to a community tank. Coloration combined with ease of keeping is what gives the Hareliquin its popularity.
These little fish are active schooling fish and rely on numbers to feel secure. They do much better if kept in a group of 10 or more. Harlequin Rasboras will happily mix and even swim together with other Rasboras and Tetras. Make sure your tank has plenty of plants and an open area for these fish to swim in.
Knowing that they like to be kept in large groups you should plan on a tank that can allow for that. Tank should be no smaller than 20 Gallons to make sure that there is space for a good sized school of Harlequin Rasboras. Always opt for the biggest tank that space and budget allow for. More space allows for a larger school of Harlequins and a larger school means happier and healthier fish.
You can tell a male from a female by the shape of their marking. The male has a straight front edge that is rounded at the bottom. Breeding Harlequin Rasboras is not very easy. Water conditions have to be just right and the tank should be in a sunny place. They will spawn on broad leaved plants.
Harlequin Rasboras will eat flakes and small live foods. They are not difficult to keep and are very peaceful. These fish are good choice for a first time aquarist and are a great addition to a community tank.
