Harlequin Rasbora
Tank & water quality
For a Harlequin Rasbora, the tank is the whole world — stable, cycled water with the right temperature, parameters, and filtration for the species is the single biggest factor in a healthy fish. Give them enough volume and swimming room, and change water on a regular schedule.
Temperament & tankmates
Some fish are peaceful shoalers, others are territorial or solitary — compatibility depends heavily on the specific species, not just looks. Research a Harlequin Rasbora's temperament before mixing tankmates, and add new fish slowly.
Everyday care
Offer a species-appropriate diet in measured amounts, test and maintain water quality, and keep the tank and filter clean. Quarantine new arrivals when you can. This is general orientation — an aquatics-savvy vet or specialist can help with specifics.
