Hello. I have a female Russian tortoise named Crush. She is approximately 9 years old and I have had her for 8 years never with any problems. I keep her in an extra large Rubbermaid tub with 50/50 coir brick and sand mixture that I just keep slightly damp. She eats mostly store bought greens. I try to get as big of a variety as I can. I live in Washington state so she can only eat weeds a few months out of the year. I have a uva/uvb light on one end for her and a log she can hide under that I keep on the opposite cool side of her enclosure. Anyway about 2 weeks ago I noticed she wasn't finishing all of her food (she always has a huge appetite and eats everything I put in front of her). It quickly progressed into not eating at all and she was super weak and lethargic. I took her straight to the vet. While I was there I noticed she had some redness on her side. The vet examined her and gave me a feeding tube and apple banana critical care mix for it ( even though I told her she's not supposed to have fruit) and some antibiotics that I have to inject her with every other day. Luckily she started eating on her own again so I have not tube fed her at all since the doctor did it at the vets office. She is getting stronger and looking a lot better. She has had 4 doses of antibiotics now. My concern is that the redness on her shell is getting worse and spreading to other areas of her shell. The vet thought she was bruised. I tried to tell her that she is most definitely not bruised, she has not fallen or been around any other animals. And now that it's spreading to other parts of her shell I know it's not bruising. I'm really worried. I will admit I have not been soaking her as much as I should have been and not been suplimenting her food with vitamins or calcium. She does have a cuddle bone at all times though. Anyone have any ideas? Any help would be greatly appreciated. I uploaded photos, I apologize if I may have put them in the wrong place. Thank you so much for taking the time to read.
