Could a brain catch and eat a goby?

I had a neon blue goby that I put in the tank and saw for a week. About 3 months later my friend ask what the blue fish was. I said I didn't have a blue fish, But had one a few months ago, but I think he died. I went to my tank and there was my neon blue goby. After that, he was out every day. Yes they are good hiders.
