The Rosy Loach arrived healthy and active. They have adapted well to my 10-gallon tank with a gentle flow. The coloration is vibrant and they seem to enjoy the live foods I offer.

I kept them in a community tank with other peaceful fish. They are active and don’t stress the others. The black spots are clearly visible and the yellow-orange hue stands out.

Easy to care for and very interesting to watch. I feed them a mix of bloodworms and sinking pellets. They swim in groups and seem to be happy in the background area of the tank.
