Keep them separate, they will not get along if she has already beaten him up though. It will only lead to a dead fish if you try anything.
The issue I see here is the fact the fish is beaten up may mean your store will NOT take it back possibly.
180l is about 45g which is bordering on the small side to add anything else to the tank. The angles are very borderline as well for a tank that size.
10g Fry / Hospital / QT tank (as needed)
75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.
220g Still sitting empty (come on Lottery I need the numbers to come up!)
