what angle are the heaters , are they near a water flow ,?
i dont think thermostats on aqua-ones are that accurate always out 1 or 2 degrees either way
also do you have a fire or heaters in room ?
back in the uk we had slow worms they are a legless lizard ,
not as common as they used to be unfourtunatley , like all uk reptiles
