Easy to care for and very peaceful in the tank. I’ve had mine for three months and it’s thriving in a 10-gallon tank. No aggression, just a calm presence. Perfect for a beginner reef setup.

The Frost-Fin Cardinal looks beautiful with the coral. It doesn’t eat much and stays active without causing any stress to other fish. Slightly shy at first but settles in quickly.

I bought this for my first reef tank. It’s small but vibrant and fits well in the community. No issues with water parameters or compatibility. Highly recommend for new hobbyists.
