Normal
Going by you saying its rump was small is the reason I thought it may have just previously molted. Brachypelma, normally, are good eaters and will eat right before a molt, or within a few days of one. My B. sabulosum ate a cricket, spun a molt mat then flipped. Next morning I removed the molt, but not without a fight. [emoji4] As long as its rump is near the same size as the carapace I wouldn't be too concerned though. I prefer mine to have plump rumps, about 25% larger than carapace. Glad you believe it has eaten, give it a day or two, then offer food again. Hopefully all is well now. Keep us posted on the progress.
