i sort of thought I would be able to smell it? But maybe not. When I took her out yesterday she seemed really active compared to normal and didn't want to be held, so maybe she is going to be shedding soon? As i haven't seen her shed before I don't really know what to look out for.
My tank is 15 gallons i think. I am going to clean the tank out properly on monday so I'm sure if she has done any I will find it. I take her out of her viv to feed her so she shouldn't have taken in any aspen. Thanks for all your help, I'll let you know what happens hehe.
