I got a new fish yesterday. I chose him because he had unique colors and seemed to be a physiologically healthy but stressed fish. He sat at the bottom of the cup with clamped fins. I thought he was just cold and stressed; he had no other signs of illness and had beautifully straight, long rays. There was a rather large black spherical thing in the cup with him. Poop or parasite egg perhaps? I cleaned out the tank, went to school, got a fish, floated the cup for a while and plopped him in the tank. He was very active and darted around, flared at his reflection and seemed to be doing well. Last night, I saw that he was laying on the bottom. This morning he just floats in one spot at the top. He didn't eat this morning. This morning I moved him into a 2.5G tank when I tested the ammonia to be high. I don't know why it would be high; I just did a 100% water change yesterday. There is one plant in the tank. He was in the part of the filter where the water comes back into the tank earlier today. I know my sister's fish uses his filter as a hammock, so I don't know if this normal or not.
