I have two RES age 2.5 years. Yesterday I took the turtles out of the pool (they have a little doggie pool in the yard) and one turtle had a circle of lighter skin on each of her back feet. I didn't remember if it was that way before but the other turtle doesn't have it. Now that she is in the h2o in the tank they look like white circles, (maybe blisters) and sometimes she tucks them in and swims mostly with her front feet. Circles are maybe bout 0.5 inch. What the heck happened to her? I hope she doesn't have to go to the vet cuz I am totally broke after i went to a reptile show and bought a gecko cuz I had to get alot of apparatus for the gecko, bless her little heart. I did make an appointment for the vet for Saturday.
Someone said take her out of the h2o. Should I? How long? Should I get medicine for it? Right now she is in a giant tupperware. I think there may be another spot on her armpit. They are not fluffy spots.
Her tank is crystal clear so she shouldn't have caught something in there. There is a canister filter, uva and uvb, and a place to bask. I put them outside some days to get real sun and I feed them out there. There is no filter in the pool but the water is new whenever i put them in it and it's only a couple inches deep. There is a heater in the tank so the water is warm but the pool is cool.
Is there anything I should be doing? Is there a way I can avoid the vet visit? I heard sulfa is not good because is makes them resistant to it but she had sulfa dip when she was a baby and the other turtle accidentally poked her eye and she got better.
