Fish I don't recommend
All of these fish are ones I don't recommend for beginners and experts.
There are freshwater stingrays, but they can give terrible stings.
There's an electric eel that has electricity so strong that it can stun a horse. Very dangerous if you have children!
Pirahnas, as most people know, have sharp teeth. I would recommend you have chain mail around your arm if you really want these aggressive fish. I don't take responsibility for lost fingers or bit arms, or whatever!
Same as the Pirahnas, Triggerfishes, a marine fish, have sharp teeth. I'd also recommend chain mail around your arm. I don't take responsibility for lost fingers or bit arms, or whatever!
