Many thanks to jaws7777 for digging up this info on vultures. My uneasiness with them grows.

Firstly, a warning:
This is certainly the most beautiful fish I’ve ever kept. The pattern is amazing, the fins are large, and the whiskers are as long as their body. They grow very large, very quickly, and are a good tank mate until they reach (what I assume to be) sexual maturity at about 10-12 inches long. When that happens, they will change overnight. A fish that you’ve been able to keep with it for years will suddenly be bullied and often killed.
I’ve read many times that these fish do nothing to earn the fearsome reputation they seem to have, and that is true, until they do something to deserve it. I kept my Vulture successfully with many different types of fish, most of which were small enough to fit in his mouth and as long as I kept him well fed, he never touched them… Then, quietly, over the course of about two months before the final attacks, all three of these fish that I have kept (one at a time) would change. They’d slowly eat smaller fish, attack bigger ones (waking up to half an Angelfish being my first indication), and gradually whittle down the tank population to just themselves.
Are they placid and nice before they change? Yes, but all three of mine eventually changed. They deserve the reputation.
With that said, let’s move on and talk about the positives of this awesome fish… Because if you want to dedicate a tank to it, or something it can’t hurt? Go for it. It’s an amazing fish.
Teeth?
Yes. Finding half a fish and a clean cut through both flesh and bone occasionally is a good indication that this fish packs a hefty bite.
