I have a 2" Red Devil Cichlid with a black spot on it's upper lip, and 2 others on it's tale and fin. I've searched but only come up with Black Spot Disease, and Black Ich, both of which Red Devils shouldn't contract. My parameters are as follows PH:6.6, Ammonia:.50, Nitrite 0, Nitrate:10. I had a spike to 1ppm in ammonia 3 days ago(added 2 Blood Parrots to 55g tank), and have been doing water changes and adding prime to bring it down. It fist got a small spot on it's lip 6 days ago, and has since grown to about 1cm, and has small spots on the tail and fin. It's eating and swimming like a champ, and I don't see anything else wrong. Tried to get a pic, but it wont stay still for me to take it with my crappy camera. I'll try to borrow a friends camera to get a good shot when possible. Any feedback would be appreciated.
