Those vets don't know tortoises. Vitamin A shots are for turtles, not tortoises. This is a tell-tale indicator that a vet doesn't know tortoises and is reading from a handbook or website in the back. Those injections into a tiny tortoise that is already compromised are likely to hasten its demise.I would say the mucus is clear with a hint of yellow. Kinda looks like when you blow your nose to be honest.
I started noticing these red spots on his shell last night and took him to the ER. They think he is septic and gave an antibiotic and vitamin A shot. Hoping to get him in with a specialist tomorrow morning.
No vet can save this tortoise. It is a complete waste of money. There is nothing they can do. Offer the correct conditions and temperatures, soak daily, and try to do your best. Some make it and some don't. There is nothing any vet can do. The damage was done by the breeder and or seller, and that damage can't be undone no matter how much you spend at the vets office.
