Bought this tang for my 120-gallon reef tank. It has been thriving for six months. It’s active and doesn’t damage corals. Feeds well on algae wafers and occasional blanched vegetables. Needs a bit of space and a strong current, but overall a good addition to the tank.

The tang arrived healthy and seems to be adjusting well. It’s not overly aggressive, but it does chase smaller fish occasionally. I’ve added some larger fish to help reduce stress. Tank is now stable and the tang is active in the middle zone.

Great choice for intermediate reef keepers. The tang is clean and helps control algae. It’s not too large for a 100-gallon tank and doesn’t cause issues with coral. Feeding is simple and it stays in one area most of the time.
