unuasual behaviour

i have my emperor scorpion nearly a year now.
the last week or so i cant keep enough water with it.
it seems to be emptying the water tray or using the water somehow.
also it seems to be standind funny with back legs at full stretch.
has anyone come across this before??
this is my first scorp,so if there is a problem id like to get it sorted asap

Sounds weird. Perhaps there is a leak in your water container...Idk about the leg thing.

no there is no leak.and its to heavy for him to tip it over.
i cant find anything to explain it.i am probly describing the leg thing/stance wrong.
ill try and get pics to explain better.

Is it a big or little container?

sure its not just evaporating?? ours has to be refilled everyday as it gradually evaporates though the day/night lol
