Lyretail Damselfish – Neopomacentrus azysron
The Lyretail damselfish is a beautiful addition to reef tanks. This species is an exceptionally hardy saltwater fish and makes an excellent beginner fish.
They have a black or deep purple body with a bright yellow lyretail that can develop long, elegant streamers as the fish matures. The typical adult size is around 2 inches in length, making them suitable for smaller tanks of 30 gallons or more.
They are not as aggressive as most other damselfish species and should not be kept with very aggressive fish. While they may become territorial toward smaller fish, they are generally peaceful toward larger species. These damsels thrive in small to medium groups and add vibrant color to the mid-level of the aquarium.

Easy to care for and very colorful. My 30-gallon tank has been thriving with this fish for six months. The yellow tail grows beautifully over time and it doesn’t stress other fish in the tank.
Virginia James –
Great for beginners. The fish is calm and stays in the mid-level zone. I noticed the tail streamers started growing after three months. Just make sure not to keep it with tiny shrimp or small fish.

Perfect for a reef tank. It’s hardy, doesn’t eat much, and adds a lot of visual appeal. I’ve had it for over a year and it’s still active and healthy.
