My lung fish has been like this for 4-5days he is 15cm he is alone in a 350l grow out tank ( dont worry i have 1100l and 2700l) amonia 0 nitrite 0 nitrate 5ppm. He got his back legs nipped off by 3 tin foil barbs wich i moved right away and they are growing back nice he still eats and acts normal.
Anyone have idea what mightbe wrong?
