I would not add any more live stock to the tank. If what happened is what i think is happening then your ammonia is going to go up, most likely to unsafe levels for the things you have in the tank. Your fish might survive but the inverts and coral are usually pretty sensitive to changes in your water parameters. You r going to want to test your water everyday for ammonia, nitrates, and nitrites until you have acceptably readings. Idk if it would be better to take out all of your livestock (if this is possible) or not at this point.
