I have a
small decoration that I picked up a petsmart a while back. It has a big hole in the back, and 2 smaller holes in the front.
My 3.5" Opaline gourami swam into the back, and got stuck in the smaller hole in the front. I walked in to the room, and saw him, and didn't think anything of it. He likes to swim into the ship and poke his head out.
As I watched though, he tried swimming out, jerking his head from side to side and straining to get out, before giving up. I ran over and pulled the decoration up and set him free, but his head is all torn up on both the top and bottom The top scales are torn up for about 3/4 of an inch, and a little less than 1/4 an inch on the bottom. (it's a slight purplish color where the scales are gone and a darkish blue around the edges, and the bottom, just in front of the anal fin, is a blackish color).
When I first set him free, he was leaning toward one side, and had changed color to a dark blue. He's straightened himself up, and his color is lighter again, but he's not as active as he was. He's been sitting in the back corner, around mid level, going up for air every once in a while. Except for going up for air, he's only moved around the tank twice in the last, hour and a half.
1) Is there anything I can do for him, other than letting him heal on his own? Do I need to quarantine him, or do more water changes, or add something to the water?
2) How long does this kind of damage take to heal? I really feel bad for him.
