Hi everybody. I've only been keeping fish for a few months and would appreciate any ideas as to why one of my neon tetras has lost the colour from its tail. The body is still blue but there is no red pigment in the tail. He was red when I got him about 8 months ago and has been like this for a couple of weeks. He seems ok in himself, he eats and swims around like the other 11 neons in the tank. Any ideas?
