公牛鯊

I've had this bull shark in my local river for three weeks now, and it's remarkably unfazed by the changing salinity levels. It patrols the shoreline aggressively every morning, just like the description said it would.

This thing came through the shallows near our dock without a care in the world, and its aggression is no joke—it hit the line like a freight train. The fact that it thrives in both salt and fresh water makes it a real threat anywhere along the coast.

I was a little nervous about keeping such a tough fish, but this Bull Shark handles brackish conditions just as advertised. It’s already made itself at home in my river-influenced tank, and the aggressive behavior is exactly what I wanted for my setup.
