Your welcome. Midas Blennies have a lot of personality and look great once they get older and stretch out. If you are looking for another Yellow fish, consider getting a yellow assessor. They are great little guys and are pretty chill for a reef. I picked up one from Fintique during their SW thursday sale and he is in my 40 breeder adding to the nutrients for my coral frags. If you are looking for more mid water fish, consider the following:

Cardinals- Bangaii (will breed in the tank), Pajama, gold stripes, red spots, practically any from the Cardinal family are great. For ideas, go to liveaquaria.com and check out the types that are commonly available. From there, either order them online or ask a local fish store to order them for you.
Forked Tail Blenny- I have one and she is awesome
dartfish- make sure you have a top. They can be really cool and have lots of color. Helferich dartfish are impressive
tangs- your tank will be a little small for these guys. I say minimum is a 4ft + tank for swimming room
Flasher wrasses- McCoskers is a flasher wrasse. If your guy is young enough, you can try to get another type of male like a carpenter. They will flash each other for dominance. If you have had your McCoskers for awhile, DON'T get another flasher
Other wrasses- Yellow Corris wrasse, 8 Line ( I don't like them for their aggression)
Fairy Wrasses- Hawaiian Flame Wrasse is a beautiful one

The next set are iffy because of care or aggression among themselves but because they are zooplanktavores, they tend to hang out on top of reefs and other fish look to them to see if the coast is clear or not:

Chromis- these can be fickle but if you feed pretty heavily and frequently, you can help avoid aggression over food territories
Anthias- I wouldn't normally recommend these unless you can feed quite a bit
