Samantha Randall –
The Lavender Tang has been thriving in my 75-gallon reef tank for six months. It’s active but not overly aggressive and doesn’t damage corals. Feeding is straightforward and it’s a visually appealing addition to the tank.
Virginia Newman –
I added this tang to my intermediate reef setup. It’s semi-aggressive, which is manageable with proper tank mates. Growth has been steady, and it’s become a regular part of the tank’s activity.
Sarah Vaughan –
Great choice for reef keepers looking for a hardy, colorful tang. It’s calm enough not to stress other fish, and it’s been eating well with a varied diet of algae wafers and spirulina.
