Got this fish for my 100-gallon tank. It’s active and stays in the back corner. I’ve noticed it doesn’t eat much, so I feed it twice a week. It’s not aggressive toward other fish, but it does defend its space. Good for intermediate reef setups with no corals.

The fish arrived healthy and looks well-maintained. It’s a bit shy at first but settles into the tank after a week. I keep it with a few larger fish, and it doesn’t seem to attack them. Tank size is adequate, and it’s a solid choice for intermediate aquarists.

It’s not the most active fish, but it’s peaceful in its own space. I didn’t expect it to grow that large, but it’s now about 12 inches. Feeding is simple, and it doesn’t cause issues with tank mates. Just make sure the tank is big enough.
