Once upon a time, I saw a thread on MFK of a guy that gave his arowana the gill curl surgery without really knowing what it looks like. All he had were after photos. I just took this video of my jardini that has a very pronounce case of gill curl. I was going to do the surgery on it but it hasn't hinder his living yet. Once it does, I'll perform. Until then, I'm not going to risk his life. Here is a video for reference just so that you will know for sure for future reference. You may want to sticky this.
