man, if my regal caught it from one of the new fish i'm gonna be so ****ed at myself. ahhhhhhh.
Sure that's what happened. You can't add that many fish at one time to a 225 gallon aquarium, especially without quarantine, and not expect problems. You compromised the water quality, added parasites, and generally stressed all the tank inhabitants. Unfortunately, it's unlikely that your regal will recover and I'd also expect the new chromis to die.
