Bought a few neon velvet damsels for my reef tank. They looked great when young, with bright blue patterns. After a few months, they started defending their space aggressively. I had to rearrange the rockwork. Still, they’re hardy and easy to feed. Worth it if you’re okay with territorial behavior.

The juveniles were colorful and active. I kept them with other species, but after 6 months, one started chasing others. Now I keep them alone. Feeding is simple with flake and frozen food. Good for experienced aquarists.

Expected a calm fish, but the adult version is quite aggressive. I added two at once to reduce stress. They’re not suitable for a community tank. Good for a single-species setup with proper space.
