As a gift, my brother got a tomato clown for my reef tank of 30 gallons. The tank also had a small clown, and yellow tang, a blue damsel, and another fish which i forget the name of but it was about the same size as the yellow tang (both about medium sized). The tomato was in there for about a month and everything is fine. However, two days ago one of the large fish died for no apparent reason. Then, the tang died with no apparent illness etc. The tomato has recently taken to a coral and seems to be aggressive toward the two fish that are in there. Could the tomato clown have killed the other two fish that were significantly bigger than it? What should I do about this?
