I was thinking the same that he was a she, but isn't weird that "she" would have such large fins? Also the area where the white thing is, is slightly pudgy. On another note, do you know why the color looks different when they are held towards the light? To answer your question, he doesn't have a heater. Right now I have him in a temporary container because I traveled, but he's usually in a 1 gal tank with rocks, and some fake silk plants. He has a light that slightly heats up the water as well but I make sure to only have it on for 30 mins or so.
