I cleaned my tank today and every thing was good I came home tonight and my one ray has a red mark on it it doesnt look like a burn it looks like it may have gotten stung by the other one it is red and looks like it got poked and is swolen and red around where the hole is. I dont know how that could happen on top of the rays disk. I know it is hard to tell what it is by pics but I tried to get some. What should I use to help it? Salt? She is eatting fine and moving around normal. Water 84-85 Nitrate under 20 ppm nitrite 0 ammonia 0
