Update! I Forgot to mention this earlier cause I am and was panicing. I noticed this morning that his tail has been trashed. It is black and grey, torn apart. There is a filter in the tank and since he has not been moving around much he just layed down by the filter and must have been there for quite awhile and gotten sucked in or at least been trashed by the filter. I don't know how else to explain it. I hope so much that I can help the Ralpinader get back to his old self. I rescued him from certain doom, he was given to me by a person who never took care of him, had him in a 5 inch by 3 inch bowl, unfiltered water, straight tap water, and they let the water get so filthy sometimes I couldn't see him!! He was given to me cause I think they knew how much it bothered me to see the fish in this enviroment. I went out scraped together money, got him a tank, heater, filer, plants, and decor. He means a lot to me, please any more advice would be great!
