Hello. I have an approximately five-year-old red foot tortoise. He has done great up to the last couple days. He’s not wanting to eat his recent food I put it by him and he just sits there. I have also discovered what looks like tiny little Beatles throughout his enclosure on his food even on him. He’s getting a complete substrate change today to get rid of the Beatles but would they be causing a problem? If he does not improve I will be scheduling an appointment with an exotic vet, which is very difficult with there’s only one in this area and with Covid there are very few openings. Any help or suggestions in the meantime would be appreciated.
