My shovel nose is all messed up. about a week ago he started swimming nose down and having problems staying down in the tank. So of course he charges at the bottom everytime he floats up which has shredded his snout. He hasn't been eating his food(he's normally a 2 fish a day pig) Yesterday I discovered taht there was something seriously wrong with his water and well his substrate was kinda rough so we did a complete water and substrate change. He seems to be better now but he's still swimming nose down and he seems to be arching his back. Anyone have a clue about what the problem might be. And don't say its the water change...cuz that actually made him stop floating to the top and his wounds are now starting to heal.
