Advertisement A. Avicularia, 2 or 3 inches. Left a crushed superworm three weeks ago, dead as hell, and it's gone-- had to have been eaten, like usual. For some reason though, the abdomen keeps getting smaller. Normal? Can pre-molters eat but change physically like this? The abdomen was black but now it's getting brownish hairs where it connects to the rest of the body. Can't get a good picture, sorry. I've been offering a new worm every night but the tarantula won't take them. I usually feed once every 1 or 2 weeks. Her enclosure has a lot of connection points and fake plants on substrate so I don't think she fell and hurt herself? Sorry if dumb I just want to be sure she's ok. When I offer wiggly worms she just walks away, so I leave them on her castle as they die from head-crushing and remove them the next day.
