Alligator? Or is it Crocodile… whatever the freshwater one is…
I have heard there are some NASTY eals out there…. But really, fish tanks are for calm ,,, imho just use neons..

Red tailed catfish will eat anything that fits in its mouth. It grows to over 3feet long though so good luck.

but this piranah is meant to try and attack your finger through the glass, aswell as eating mice and rats that you put in the tank.

What size tank will it be going in?

Cory cats are the most vicious creatures ever to scourge the planet.

You could also try otos. They get really mean and nasty, especially when there's lots of algae.

Mollies and platys are practically the devil incarnate.

Okay okay...all kidding aside. How about a D. Cheneyensis? Tell me this is not the face of pure unadulterated evil:

Red Devils.

'Nuff said.

A snakehead is the meanest fish. I used to own one many years ago. They will eat anything you put in their tank and try to bite anyone who walks past. Mine used to hit his face on the glass so hard trying to bite someone that he would bleed. They are now illegal though and you probably wouldn't be able to get one.

How big of a tank are you getting? Most of the "mean" fish need a large tank. If you plan on feeding them live food mice and rats be prepared to do a lot of water changes.
