It seems like now would be the time to do something. Could it heal and be just fine with it protruding? Seems like it's in a lot of pain. Thrashing all night. Does it need to be put down?
Don't you think netting the aro Would cause a lot more stress and possibly further damage?What I would do if I were you is seperate the fish immediately. Put the arowana in a seperate tank. Treat him with salt or melafix and heavily airate the tank. You might also want to use pimafix to prevent the wound from becoming infected or growing fungus. Depending on how bad the wound/bone sticking out I would possibly try and apply a liquid bandage of some sort BUT only if it's placed in a seperate tank that is heavily airated.sedate the fish first. try to push the bone back in place before the liquid bandage/adhesive is applied. I've heard of this process being done with expensive and high end koi fish but have never done it myself so Research the topic a bit yourself I'm not sure what types of liquid bandage are safe or not.best of luck and please post pics, water parameters, and any other info you think may be helpful.

Who said you were to use a net? Lol. The best thing to do would be to use a towel I think. Get the towel wet and guide him in it and lift him out simple as that. That's how I moved my RTC with no hassles or struggle. Then take him to the desired destination. I mean that's how I have moved large fish with no struggle or issues in the past. Or even better sedate him if your really expirenced.Don't you think netting the aro Would cause a lot more stress and possibly further damage?
Alive and well. Was eating as usual the next day. Now the lower jaw bone sticking out is starting to curl down but doesn't seem to bother the aro at all. A guy at my LFS told me to wait til it starts to turn yellow and lift em out with a towel and clip it off with scissors or something.any update on this fish?
