Added a Sharpnose Toby to my 40-gallon reef tank. It’s active and doesn’t harm corals. Feeds well on small crustaceans. Needs some space and a stable environment. Good choice for intermediate reef keepers.

The fish arrived healthy and has been active since setup. It’s semi-aggressive but doesn’t attack other tankmates. I appreciate the reef compatibility. Monitor feeding habits closely.

Perfect fit for a mid-sized reef tank. It’s colorful and stays calm around other fish. Only needs a few inches of space. Easy to maintain with proper diet.
