Fish List - Limited Tank

[noteworthy]

I have the following:
2 Yellow Tail Damsels

Looking to get the following:
2 Clownfish


I like the look of the following but I don't know how practical they would be going in my 55 gallon tank.
Tang - really need 75 gallon?
Angel - okay in 55?

These I don't know how many I should get or even if I should get all of them... what type of cleanup crew.
Cleaner Shrimp
Miniature Crabs
Snails


What else do you think would go well in a 55? Please give me numbers so I can pair them up if they need to be. I've got poor lighting and 30 lbs of live rock.. seaclone skimmer.. penguin 330 filter.. extra powerhead in the corner.

You may run into aggression problems with the damsels. They can be pretty mean. A dwarf angle, like a flame or coral beauty will be fine in a 55. Start with a couple cleaners, a dozen reef hermits and 6-10 snails.

So just the clowns.. angel.. maybe keep damsels and cleaner crew?

I saw some gobies. Atleast I think they were gobies. Really a dark brown and they were all over the sand bed scavaging.
