Damsels and clownfish are hardier fish; most start with one of these. Damsels can be aggressive.
You should get a vision on what you want in your tank and plan from there. Some don't like to buy fish and then take them back later.
If you need a list of fish look on this site: <a href="https://www.saltwaterfish.com/order1.html" target="_blank">https://www.saltwaterfish.com/order1.html</a>
It gives you list of inverts/fish, plus a pic and some basic info (how big, what will eat)
Keep in mind your tank size,
When in doubt ask.
