1. Bicolor Blenny

The Bicolor Blenny is a small, peaceful fish that makes an ideal beginner pet.

They make a great addition to any nano reef tank and will help to keep your aquarium clean by sifting through the sand for food.

Yellow Prawn Watchman Gobies are native to reefs in the Indo-Pacific region, so they’re used to living in a warm, saltwater environment.
