The Lavender Tang has been in my 100-gallon reef tank for six months. It’s active and doesn’t damage corals. I’ve had to monitor feeding times to avoid conflicts with other fish. Overall, a good addition to a mature reef setup.
Oliver Brown –
This tang is healthy and colorful. I kept it in a 75-gallon tank with a mix of soft corals. It’s not overly aggressive, but it does chase smaller fish occasionally. Needs a bit of space and stable water conditions.

Great choice for intermediate reef keepers. The fish is vibrant and stays calm in a well-established tank. I appreciate the clarity of the species description and care requirements.
