I have a 29g and I'm not quite sure what I what

I was thinking of a damsel tank (yellow tails & chromis) with a maroon clown. Think the maroon could hold his own with damsels? But I would also like a yellow watchman goby. Could all these be housed together??? It would be a cool splash of color!!
Looking for all fish advice
please post what you would do, but they have to be reef friendly
