Yes there are lots to choose from. dbgator1 gave you some examples, the firefish are really pretty, I love my bicolor blenny they are fun to watch. There is also the yellow clown gobies, these are tiny and colorful. Take a look at the fish on this site and just go through what there is for gobies and blennies. There are also other sites that you can look up the different types of gobies and blennies on the web too.
Because you have the clown in there already, sometimes putting another in there of different size will work and other times not. But if you put something in there like mentioned above then there should be no problem at all.
Good luck and let us know what you get....
