I had a cat when I first started my saltwater hobby. I was new to the reef world and had a 55 gallon open top. Came out of my room one day and looked down the hall to see my cat sitting on the edge of the tank, munching on my clown fish that was in her claw. She decided to have fresh sushi that morning and ate my clown, flame angel, bi color angel, fire fish and my anthias. Needless to say, she found a new home within 24 hours. I now have two cats but a reef tank with a canopy.
