Advertisement This is my first tarantula and i have had her for about 2-3 months. I got her when she was 5 months. I think she is a b.smithi but it just said red knee on the tub. Anyway she has not molted since i got her, but i think she might be in premolt now. She has not eaten for almost a month but i cant tell if her abdomen in getting bigger. But she has been twitching her legs. Is this normal for premolt? The substrate looks really wet but thats what it was like when i got it. I am going to get a better substrate for her.
