Great for cleaning the bottom of the tank. I noticed less algae buildup after introducing the fish. However, I had to separate it from my smaller community fish after a few months as it started showing aggressive behavior.

The fish arrived healthy and seems active. It does eat algae well, but I’ve had to keep it in a separate tank from other fish to avoid stress and fights.

A solid choice for algae control. The fish is hardy and stays active. I only keep it alone now because it gets territorial as it grows older.

Works well in a planted tank. It doesn’t damage plants and helps keep the substrate clean. Just make sure to provide enough space and avoid mixing with small fish.
