Generally I'd say no, but you could try it. They will eat most of your clean up crew. Those teeth are made for crushing shells, so it will get most of your snails and hermit crabs. It will also get shrimp, if you have any of them. They might eat smaller fish, but just about anything will do that.
If your going to try it, have a plan B in case things don't work out. A lot of this depends upon the individual fish.
