Hey there..
I posted that thread few month ago and with the advice you guys gave me she ate once, at that's all.
Last ate was at- 17 of November, 2017
she weighted 427 at the beginning of November 2017.
At the end of January she weighted 433 so I don't think she losing weight.

What else can I do to make her eat?
Should I try tuna scent \ blood scent or what else?
Tried thawed mice \ rat, live rat \ mice and fresh killed rat. She ate both thawed and live mice \ rat at the period when she ate "good".

Hot side 84-85 f, plastic tube with under tank mat, no hide spots.

Notice-
When I first brought her she did problems with feeding to the previous pet store owner (he didn't tell me about this!), after a month or 2 she ate at my place for around 3 month's weekly feed live and thawed mice, took a break from eating for another 3-4 month, ate once at last November and didn't eat till now.
I don't handle her at all since she last ate, even month before that.
