I've had this ray for 8 months. He has eaten since day two and is still eating like a maniac, but yesterday I noticed the tip of his tail is now white. I looked at it again today and am now worried. It looks a tony bit fluffy. I just dosed the water with a small amount of aquarium salt. What else should I do and should I be worried? I don't know how it could have been injured. Pics!
