Justin Churchill –
The Lavender Tang has been in my 100-gallon reef tank for six months. It’s active and doesn’t damage corals. I appreciate its color and movement. Feeding is straightforward with high-quality flakes and frozen foods.
Michael Metcalfe –
It’s a beautiful fish with a calm demeanor once settled. I had to be careful with tank mates, but it’s not overly aggressive. Needs a large tank and consistent feeding.
Lisa Ogden –
Great addition to my reef setup. The fish is vibrant and stays in its territory without causing issues. I’ve observed it grazing on algae, which helps with tank balance.
