FossilReef thank you so much for the input. I saw a sailfin and a yellow tank in the same tank (given it was prob at least a 250g) and they seemed fine so I thought it might have been possible. I will cut the yellow tang from the list. I will def put the Coral Beauty and Flame Angel in at the same time, hopefully they will work out!

Anyone have problems with butterfly fish and corals together? Could a puffer be added to this list?
