Other hardy corals to add?

[XeniaGirl]

Long time no see... hope everyone is doing well.
I have a 12g NC that's been going strong for about 8 months now. I currently have:
-lots of green and red mushrooms
-lots of xenia
-1 maroon clown
-1 twin spot blenny
-1 scooter blenny
-6 reef hermits
-1 sand sifter starfish
-1 fuzzy hat urchin
-3 small snails

I'm looking for ideas for hardy corals, preferably of a bright color, that I can add to my tank. All the tank specs are great, basic lighting (which can be upgraded), tank temp stays right around 81F. I do a water change once a week and add RO water throughout the week (usually once every day/other day). I have live sand and live rock but just removed a few pieces so I have room to add more!
Thanks in advance!

leathers,zoas,some low light LPS such as favia & maybe hammer, maybe some sponges,

oops! I forgot to mention that I also have green button polyp (or maybe they're zoas, I really don't know).
I hadn't really thought about leathers - what else could you tell me about them?

[ChilisREasy]

button polyps are a lamen term for a type of zoa..theres several different kinds..i would need a pic to Id it correctly. as for leathers..they grow fast depending on lighting but will do good under almost any lighting..besides cabbages..i have little luck with them under 130w-10k PC. get a toadstool leather, or a colt. they should do great..be sure to run carbon as they can kill other corals with toxins. could you post the wattage of your lights please..then i can tell you exaclty what you can support

fungia.....and they can come in a multitude of colors.
