Dorothy Hamilton –
The Lavender Tang has been a great addition to our 100-gallon reef tank. It’s active and doesn’t damage corals. We’ve had it for six months and it’s thriving. Feeding is straightforward with a mix of algae wafers and spirulina.
Molly Stewart –
It’s semi-aggressive, so we made sure to keep it with larger, calm fish. It’s clean and helps control algae. Needs a spacious tank, but worth the investment for reef balance.

We bought this tang for our new reef setup. It’s active, colorful, and doesn’t seem to harm the corals. The fish has adapted well to the 75-gallon tank and is eating regularly.
