What kind of shark, what size tank, and what other fish are in there?

It sounds like the only thing you can likely do is remove the shark to another tank or return him to the LFS. Many "shark" type fish do become mildly aggressive as they mature. In most cases, this type of fish won't lose its aggression by adding more of its kind (generally loners and aggressive to conspecifics) or rearranging the territory in the tank (like you can do with some cichlids).

The rainbow shark needs a larger tank than what you have.

How is it okay to have a semi-aggressive fish that is going to grow to half a foot OK in a 20 gallon tank with angels? Ask them that.

ya they told my brother he could have 3 in his ten gallon so he bought them and one died and he gave me the second smaller one

So he still has one in the 10 gal?
