I have a pancake hatchling hatched late Feb I think. I have owned a couple months now and she has been sick for three weeks or so. She looks very dry and has a lot of what looks like hard water around her mouth. Her eyelids are swollen. I have taken her to a very knowledge reptile vet who said she had an upper respiratory and put her on antibiotics. She has had four doses of injectable fortaz so far with no improvement. We recently added meloxicam and eye drops which still haven’t change much. She is in a 48x32 terrarium with a full tank T5 10.0 UVB bulb, CHE and a night heat bulb. She is on ecoearth substrate. Heat on the hot side is mid to low 90s. I originally had heat around 95-98 when she first got sick but was advised to lower the temp. Temp at night is around 72. Cool side is between 72-75. Humidity was around 60% when she got sick. I bought a misting system which I have set to go off twice a day raising the humidity to 75-80%. I have a humid hide and multiple regular hides. I soak her everyday for 45 minutes. She gets calcium 4 times a week and vitamins once a week. Since she has been sick, she has been getting calcium everyday per the vet. She is still fairly active and is still eating well. My vet is not sure what to do next. I need some advice. Trying to schedule an appt with UCD but it is slightly difficult with COVID.
