So, I was scooping some extra food out of my tank and rested the net to dry between the hood part that lifts up (I do this all the time when I use the net). The actual hood was only open maybe an inch or two. Anyway, my DG jumped out of the tank onto the floor. I don't know how long he was out, but when I found him, he wasn't moving, but I tried to put him back just in case. To his luck, he was still alive, but barely! I noticed his fins some how got ripped in multiple places (I'm assuming from him thrashing around on the floor), and his face is very bruised and he is now gasping and swimming a bit cocked to the side, but only a little bit before going back to the bottom of the tank for a rest. He fell about three to four feet to the ground. Is there anything I can do to help him? I love this fish he is my first fish that wasn't a betta.
