The reason I use the pedialyte is for the glucose and hydration. You can also use Gatorade now that it no longer contains HFCS. A starved fish I believe is also dehydrated. Stat is what some of us in the shark world used for neonate pups that wouldn't eat. tube feeding sharks is nothing new and the formulation of stat and pedialyte is not my creation, but I thought I could be successful with fish. Before starting, I searched everywhere and found not a single source. The clown that in the video was my first attempt. There I used mashed/dissolved flake food. It was a healthy fish. For an imaciated fish I wanted to try a high caloric diet and since I had stat In my fridge, it fit the bil. I've also used the mazuri fish diet with menhaden oil as a gruel, but the blender took forever to clean. It is interesting to hear that live aquaria and others are doing it. I wonder what they are using. I first tried the cordis from a central line, it worked well but the kit was very expensive, I had trouble with silicone tubing, but the angiocath was perfect. The problem is that you likely need a prescription to buy them. Even with the needle removed, it sounds like they may still be lost in the mail. Hopefully the next will arrive. I first posted this in video 2012. You are only the third person to contact me about it, Derek and Peter being the others. Hopefully more will follow. I think It could help a lot of fish.
