I bought a group of Harlequin Rasbora for my 10-gallon tank. They’ve been active and colorful since day one. The black stripe on their bodies really stands out. They don’t need much space or special care, which makes them perfect for a new fishkeeper like me.

These fish are a joy to watch. When they move together, the shimmering effect is beautiful. I kept them in a community tank with tetras and they get along well. Easy to maintain and very affordable.
