What could i put in this tank ?

Yes you have cycled long enough,you will need a couple of hardy fish in the tank to create the correct bacteria for any other fish for about 2 weeks, cichlids are good and colourful, however they are territorial when breeding if there are plenty of hiding places you will be fine. But there are plenty of different fish for this size tank. I will probably get a thumbs down for this but if you get a couple of fish 1 week and go to get some more another week you will need a quarantine tank to make sure they do not p any disease to your original fish. Good Luck
