It makes little sense to be recommending fish without knowing anything about the water parameters or other factors. So, Classy...
Is this tank 180 liters or gallons?
What are your water parameters (GH, KH and pH) for your source water? You can ascertain these from your water authority if you don't already know.
Angelfish...do you know much about this species? How many are you intending? Will they be commercially raised, or wild caught (since you are ordering, either might apply)? Temperature becomes a factor depending.
Generally linear fish are not advisable with angelfish, so the disk-shaped characins work better. But the answers to the above questions will allow us to offer you better advice.
