Water Parameters For Harlequin Rasboras
These fish require little maintenance, but you should make sure that you’re providing them with comfortable living conditions so they can stay healthy and happy.
Water Temperature- The harlequin rasbora lives in a tropical climate where the water is warm. Extremely high or low temperatures are not good for the fish as it lives in water where the temperature is between 73 to 82 F.
Water Flow Rate- Most species of rasboras are extremely vulnerable to poor-quality water. It’s the same case for harlequins as well. The health of the fish is likely to decline in a dirty tank or if the water flow is too high. The species prefer slow-moving water. Nailing down this aspect of caring for the fish will definitely promote better health among the pack.
Ph Level- In nature, these fish will live in freshwater. It doesn’t live in brackish water and prefers slightly acidic water between pH levels of 6 and 6.5. The fish is extremely sensitive to any sudden changes in the pH of the water. That’s makes it very important to pay close attention to this.
Water Hardness- The species prefers a hardness level up to 12 dGH. Maintaining a hardness level between 2 and 12 is recommended to keep your fish healthy. Harlequins thrive in harder waters as it’s close to the conditions of their natural habitat.
