I'd say yes, as long as you are certain your water parameters are good. Excluding those factors, you will come to learn that bta's are unique in their behavior, in my opinion. One day they look fabulous and another day not so much. They have cycles of being lush and full of fluid which change to days later looking a quarter of their size and hardly extended. I'm sure others will respond, but from all that I have read and experienced, these are their elimination cycles as well as growth cycles. After seven years of keeping them, my original one is now six. Given time, you'll start to notice patterns in their behavior. Like many inhabitants, mine shrink as the lights dim and turn off for the night and then inflate as morning/mid-day progresses - my lights start coming on around 1:30 and don't ramp up till about 3:30. I'd give it some time to acclimate before freaking out. Check your water parameters, refresh your carbon and enjoy the little guy.
