Help me fill my tank

[Craigelsx]

I have purchased a eheim vivaline 180l tank and got a eheim professional 4+ 350

Now I need to plan what I'm going to stock it with it have changed my mind a million times its so difficult to decide this will be my first ever tank .

I definitely want German blue rams or electric blue rams but understand I need to wait until the tank is mature enough for them so until then what would you suggest .

I like cardinal tetra , rainbow gourami what other gourami are good ?, cherry barb, boesemani rainbow fish, bleeding heart tetra, cocatoo chilid the triple red ones

What would you recommend.
