I have an African Lungfish that I got from my biology teacher 2 years ago, he has been in the same tank with a koi/goldfish mix for over a year and a plecostomus for almost a year now. He can't eat the gold fish/ koi mix because she is to big and he dosent mess with the plecostomus because he use to be in a tank with one before I got him. I keep the water warm and change the filter regularly, I dont treat the tank with any chemicals because I believe it kills off the fish. Recently I have noticed that his "legs" have white on the end of them and they look slightly shorter then they normally do. His tail as well now has white on the tip of it and it is not slimy like the rest of him. I actually dont know if it male or female so I dont know if that has anything to do with it or not but I am worried and dont want ot loose him. I have been obsessed with him since the first time i saw him in my teachers class. here are a couple pictures I got of it I hope they are good enough.
