I have one of each in a 75 gallon and they get along fine. If you have a lot of rock to hide in, they will probably be ok.
Just keep doing some research on what is out there. In your sized tank your options are HUGE! There are some really cool fairy wrasses, gobies and blennies that would do well in your tank. Heck, there are even a couple of neat dwarf angels that would do ok. Not all of these together mind you, but just some things to consider.
