Went to the store to purchase some tubing...came back with another fish. (you know how it goes...)
Yet another tang. This one is an Achilles Tang. As soon as he arrived, the Yellow Tang attacked. It is funny because I would have said that the yellow tang was the bottom of the tank pecking order until now. Also, while the yellow tang and Naso Tang are best buddies, the Yellow Tang clearly dislikes the Achillies Tang.
Within a few moments, the Achilles had its tail fin sliced completely in half. The tank is now having an extended "nightime". The Achilles does not seem to have his tail blades, so he can't really even mount a defence. You may be able to see the sliced tail in this photo.
