ok, I have a 55 gallon tank that is currently empty. I want to get some cichlids but have no clue where to start. here are 2 quick shots of the tank:

I understand I'm going to need to get new fixtures/plants and was hoping someone could give me some ideas of what the best things I could use are.
I was told that I could possibly have as many as 15 of them in the tank but I'm thinking I may only want around 8 or so max. I'm also thinking no bigger than 6" in size and if smaller that would be fine as well. what are the best breeds that can be mixed without problems?
I have other questions but I'll go with any help on these I can get 1st. thanks.
