The Longnose Spotted Unicorn Tang is a striking addition to my 150-gallon tank. It’s peaceful and active, showing off its spotted pattern well. I’ve had it for six months and it’s grown steadily without any aggression. Only recommend for experienced keepers with a large tank.

Beautiful fish with a unique appearance. It’s not aggressive and stays calm even with other tangs. I’m happy with the coloration and activity level. Needs a large tank though, and I had to adjust my feeding schedule to match its appetite.
