Hi Everybody. This is question I have been racking my brain with for a while now. What in the heck are the spikey looking things on the bottom of angelfish's gill covers for? I havent seen them used for anything yet. Are they for defense, offense, just look cool, or what? I mean most things on animals serve a purpose or they fade away. They have to be for something. Anybody know what? Or have a idea or a guess? Steve
