Welcome to AA!
First off, let me apologize because I hate giving bad news to someone right off the bat. Your 75L (converting to just under 20 US gallons) is probably too small for the clowns and blue chromis. Most of these requires a minimum 30 gallon tank due to their full-grown size and if you are talking about multiples and a school of fish then the tank needs to be larger accordingly. With anemones I assume you will be wanting to use live rock for placement which takes up a lot of space in the tank, making it even smaller for the fish.
With a 75L you might want to consider a goby or firefish with your inverts. They have nice coloring and are fun to watch.
Sorry for starting off with a negative note and I am not trying to hate on you, just looking out for your wallet and the fishes welfare.
