Molly Skinner –
The Convict Tang arrived healthy and active. It has adapted well to our 80-gallon reef tank. It’s peaceful and doesn’t bother other fish. We’ve seen it grazing on algae without causing any damage to corals. A solid addition to our tank.
Kevin Hudson –
We’ve had this tang for three months now. It’s active and stays in the middle of the tank. The size is within the expected range. It’s not aggressive and doesn’t chase other fish. Good for intermediate reef keepers.
Jan McGrath –
The fish is vibrant and shows good coloration. It’s easy to spot in the tank and seems to be adjusting well. We’re happy with the care level and compatibility with our existing reef setup.
