Owning a saltwater tank is not like owning any other animal. It takes more time and more money than you think.
If you're serious about this, walk over to your tank, empty the water, and turn off the filter, then go to a book store and pick up a book called "The Conscientious Marine Aquarist: A Commonsense Handbook for Successful Saltwater Hobbyists" by Robert M. Fenner.
That book goes in depth on the products you need and the different types of tank setups you can invest in.
I really don't mean to sound harsh here, but I'm just making an observation and it seems like this may just be a passing fancy. And this is not a good hobby to have a passing fancy for.
Edit: Also, the most common bright yellow fish is prbably a yellow tang, or possible a yellow wrasse. Both of these fish will be too large for the 10 gallon tank.
Edit again: Check out this thread also.
