our twinspot beat the living hell out of a mystery wrasse larger than himself. mystery wrasse laid on the bottom of the tank for a day with no fins and blood leaking out its mouth but somehow recovered. the twinspot also beat the crap out of our firefish and tailspot blenny. we gave him to a friend and the hog beat the crap out of his watchman, killed a mandarin and was harassing a potters wrasse before being pulled from that tank. i was a big fan of the twinspot, wicked fish, but im a bigger fan of having a variety of fish.
