The Peacock Gudgeon is a stunning addition to my nano tank. Its vibrant colors and active behavior make it a highlight. I keep it with one other gudgeon, and they coexist well despite being territorial. Easy to care for and maintains a lively presence.

Beautiful fish with unique patterns. I noticed it moves around the bottom and mid-level of the tank. Feeding is simple with frozen brine shrimp. Needs a group of at least two to avoid stress.
