I bought a school of six Harlequin Rasboras and they’ve been thriving in my 10-gallon tank. They’re active and colorful, and they don’t bother other fish. Easy to care for and very peaceful.

The fish arrived quickly and looked healthy. I kept them in a community tank with tetras and they get along well. They swim in groups and add a lot of visual appeal.

Perfect for a small aquarium. They’re active, not aggressive, and enjoy the water movement. I’ve had them for three months and they’re still vibrant and active.
