that small, just take off the head and skin it.... (fins too of course and intestines lol)

then just use the mix i said above and fry him... you can deep fry him if you have a deep fryer, but if you're gonna do it in a pan, just make sure the oil covers him halfway, and flip him after a few minutes (medium-high heat, he'd be too fat to flash cook, but you wanna cook him fast)
