I have a Tortoise that is small and has runny nose with bubbles on his nose(rarely). It sneezes often, while wiping his nose with his tiny arms. It has great appetite and he has been like this for about 2 months. Also its always looking for dark places to sleep. It isn't as active as it was before i moved it into my room. First time it was running around, exploring my room like racing car, now it just goes to one of the shady places in the room and sleeps all day. I have set up a platform on the floor with mercury light bulb heating it and that's where it eats. I don't really put it in its box where substrate is,except at night or when i leave the house. Temps are around 34 Celsius on the platform. It usually goes under the paper on the platform or wanders off in the room to find a sleeping place. I feed it dandelions with calcium +d3 and multi vitamin powder. I use ExoTerra products. So what could be the problem thats causing this? Dust on the floor?
