It actually is very good for sick dragons. However I don't think I would make the bath solution that concentrated, but it helps sick dragons get electrolytes back in them and helps hydrate them.
Pedialyte is a much better option compared to Gatorade.
When Lilly was having some issues her vet recommended pedialyte baths to make sure she stayed hydrated. We used 1/3 pedialyte to 2/3 water. Gatorade has too much other stuff in it though so I would not use it.
I just set Swordtail's timer for his bath and paused it so I could actually fill his soaking bowl up and he crawled over my phone and canceled the timer
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
