I have a 20 gallon tank that is fairly well established. The inhabitants were 8 neons (4 of which have since been moved to another tank), 5 rasboras, 4 black emperor tetras, 4 pygmy corys, and 1 endlers livebearer. About a 1 1/2 months or so ago one of the neons started losing his color and white fading on the tail and I have since noticed that his tail has become bent. From above he looks almost like a "Z". He was schooling with the other neons just fine, but I moved him to a quarantince tank as a precaution. None of the other fish have any simptoms. The water is about 76 degrees and the pH is at 6.4.....Does anyone have any ideas?
