Aggressive or passive? Reef-safe or not? It's usually easier to state what you want as there are several vendors on board who have or can get anything.
Like Dean said! Do a little research, decide on what type of set up you intend on having first. Then move on to what type of fish would be best in that set up, and then which would be your favorites. My best wishes for a beautiful, healthy aquarium.:usa1:
If you want a single fish then this forum may help but if you are looking to stock a tank then as advised above, make a list and then either go to an LFS that has a big selection or go to on line sellers and get what you want.
See what works with what. Then check out their main site & look at some of the fish you might like to keep. Make a list & refer to above chart. You can also google some of the fish names which will give you links to other sites as well.
