dayak;4903610; said:pic would be good, i have seen an aro that problem, although it does not look like a live threatening desease, its ugly and sad to look at.
sounds like the desease is about to start?
if it is theres very much still a chance to fix it before u do the surgery.
i might be able to help if its not too late
It is life threatening because the gill covers play a major role in water being pumped over the gills and it is not a disease. It is a condition brought about by keeping an arowana in a tank that is too narrow for the fish to turn around without bending it's gill covers.

Honestly, just stop trying to recover, its not working. You clearly have no idea what you are talking about so just stop. Like...just stop.
