His bright yellow color attracted me to him. After noticing his frontal horns and watching his blues fins pulse in the water which made him appear to be hovering, I was really taken in. I watched him for awhile, and might add, took no less than 50 photos of him. This “longhorn cowfish” was living in a tank labeled poison fish. I had not seen anything like him before. I did a “google” search and found, when stressed it can exude deadly toxin and is capable of hovering. This cowfish is a very slow swimmer making it easily caught by hand and will make a grunning noise if taken from the water. I could have watch him for hours. The photo is pretty much true to his size.
