The Long Horn Cowfish Juvi S arrived healthy and active. It has adapted well to my 20-gallon reef tank. The coloration is vibrant and it doesn’t seem to stress other fish. Easy to care for and a great addition to a small marine setup.

I’ve had this fish for three months now. It’s been very calm and doesn’t chase other fish. The tank water parameters are stable, and it’s thriving. A bit shy at first, but now it’s exploring the tank regularly.
