I added this fish to my 75-gallon reef tank after researching compatible species. It has adapted well and is active during the day. I noticed it occasionally nips at smaller invertebrates, so I’ve added some larger rock formations to provide hiding spots. Overall, it fits well in the tank and adds visual interest.

The fish arrived healthy and has been active since setup. It’s not overly aggressive, but it does chase smaller fish occasionally. I’ve adjusted the tank layout to reduce stress. It’s a good fit for intermediate reef keepers.

After a few weeks, the fish has grown to about 1.5 inches and is now a regular part of the tank’s activity. I appreciate the clear labeling and accurate description. It’s a reliable addition to a balanced reef system.
