The Calico Bristlenose is a striking addition to my tank. Its colorful pattern stands out, and it’s been actively eating algae on the glass and wood. It’s calm and doesn’t bother other fish. I love the way it looks and how it helps keep the tank clean.

It’s a beautiful fish with a unique appearance. I noticed the bristles on the male after a few months. It’s not aggressive and prefers to hide in the driftwood. Good algae eater, but does need some cover to feel secure.
