Fish compatible with a 50g(36x18x18)

Just putting together all the equipment for a 50g mixed reef. It will be mostly zoa/lps. I have been researching fish but every fish I seem to like needs a bigger tank or something else. Was hoping to get some recommendations on what others have kept in tanks of similar sizes. Looking to have a beautiful mix of colours/shapes/sizes as I can only have a few fish in a tank this size. Any and all help is much appreciated.
 
I will list what I had been looking at hopefully that will help with responses.

clown goby(maybe 2 different colours)
Wrasse(carpenters maybe 3? or can I get a couple different individuals?)
Starcki Damsel
Dwarf Angel(coral beauty, flame, lemonpeel)
 
Those fish are doable in a 50 gallon. However, the angels may pick at your corals, especially LPS. I believe lemonpeels are one of the less cora-safe dwarf angels. Also, clown gobies can be a bit of a challenge.

There are a number of smaller fish you could do - clowns, tailspot blenny, cardinals, possum wrasse, assessors, chalk bass, royal gramma. Barnacle blennies are a riot.

What makes clown gobies a challenge? Live Aquaria and my LFS have them listed as easy care level.
 
A lot of them won't take prepared foods. If you're tank is well established they may be able to survive by foraging pods, but in a new tank there's a risk that they could starve.
 
I would not recommend the lemonpeel angel as the one I had was an 'evil' fish. He killed his only tankmate in my 65g which was a pink spotted goby and apparently this level of aggression is not uncommon with that type of angel. They are gorgeous though.

My experience with flame angels has been poor; I have not been able to obtain a healthy specimen and if you did not know, they require a very mature system to do well. The ones I tried only lasted a few days with one dying while it was on hold at the LFS!

Coral beauties can be gorgeous, but you are rolling the dice with these fish. The one I had was a terrible coral nipper, would never let my toadstool leather open! I nearly lost the leather, had to move it to a different tank.

Other fish suggestion:
- Blennies ( I think these are fun fish although I am not a big fan of the lawnmower blenny)
- Royal Gramma
- Hawkfish if you are not planning on keeping ornamental shrimp
- Cardinalfish
 
Ok removed dwarf angels from my search. Added dottybacks not sure if they can be mixed though.

Starcki Damsel
Orchid Dottyback and Indigo Dottyback(can they be kept together if added at same time?)
Carpenters Flasher Wrasse 2 or 3
Black Percula Clown
 
Here's what I would do:

Black (onyx?) percula clowns: One pair; OR
Starcki damsel:One; OR
Flasher wrasse: pair or trio; OR
Dottyback: One of either species (a 50 is too small for more than one dottyback--they're very territorial)
 
My thoughts:

-Clowns
-Chromis
-Yellow Watchman Goby
-Flasher Wrasses
- single anthias
- bangii cardinals

I love my flashers. I think a trio would work in your tank. Two males would fight.
 
I am just trying to get as many different colours represented as possible.
I am not particularly set on any fish.
Would a black cap basslet be better or worse then the orchid dottyback?
Is there some other wrasse that would be compatible with carpenters but blue in colour?
 
Look into a cherub angel also known as an Argi, and checkout the Flameback angels. These are known to be a little hardier angels and rarely grow more than 2"s in a home aquarium. I have never heard of either of these two nipping corals. I have an Argi in my mixed reef for 3 years now and it has been fine. Word of caution though, add the angel last to the tank as they can become aggressive towards newcomers.
