i have a tsn with real bad gill curl i tried every thing but failed. now i just got a 6" rtc with it it's in a 4',2',2' i have been doing 40 water changes everyday since i got it but it seems to have no change. but i managed to raise my first one with no drama so anyhow i thought everyone could use this as info thread

I have fixed gill curl on two different fish now without surgery. However, if it has reached the gill plate, it has gotten too far along to fix it with this method. I pull the fish out and place them in a container small enough that they don't dart around, but large enough that you can get your hands in there (for my big TSN that required a large rubbermaid tub). I then hold them while still underwater, and then rub the curled gill cover between my index finger and my thumb. I rub the soft gill cover for about 5-10 seconds, and then let the fish breath and check to see if it has started to lay down. Basically the goal is to soften the tissue of curled section focusing on the tissue that is normally on the inside. I add Prime to the water in the container, as well as a broad spectrum antibiotics to act as a topical. I did this procedure on my TSN. I just held so that he felt physically supported underneath and around his 'chest', and he was actually very cooperative. GL, and I hope it's early enough that you can still use this method, and hope this explanation makes sense. Let me know if you have questions. 
Can you get a picture of the fish? Do you know if it's gotten to the gill plate? Also, how long did you rubbing the gill cover? With my arowana, it took several 10 second repetitions to get the cover to lay down.

Sorry, don't know if I'm just tired, but I'm not understanding... When you say its at the gill cover, do you mean its still only on the soft tissue or has it hit the gill plate? Also, what do you mean by 'flaps back'? Is it continuing to curl or is it starting to lay down?
Gill curl is usually caused by ammonia, but a temperature drop can cause it too. My rtcxtsn vomitted once after ingesting gravel and caused an ammonia spike just after a water change. 
I didn't realize there was a problem until the next day when my tsn got gill curl. I did some research, used this method, and his gill is perfect. My arowana got gill curl and I was baffled. His water parameters were perfect, but then I realized I had accidently left the heater unplugged. The temp had drop 8 degrees in about 2.5 hours. Researched if this could have been the cause and sure enough it's happened to others. Again, used this method, and same result. His gill is perfect. I fixed both of them within a week of it happening, and the aros gill curl was fairly bad sticking out at over a 90 degree angle. However, both were caught before it hit the gill plate. This was my experience. Once it hits the gill plate, your only option to fix it would be surgery. I'm not sure if it's worth it and someone else would have to help you there.
