Of course, I am thinking the worst - ammonia poisoning, or something along those lines. He had a couple of red spots on the fins and on his face, but all of a sudden now there are vivid red streaks on a couple of fins, particularly the anal fin, and a streak just right of his eye. I really wish this just looked like a spontaneous color change, but....it's suspicious. Ideas of what it is, or maybe how to treat whatever it is? He is in a one gallon, unfiltered, unheated until I get him a tank and gets 100% changes once every two days.
