I brought home some new FBT on Saturday. They seem to be doing good, they hide a lot and like to just hang out in the water. I put in some crickets for them and they haven't eaten at all. I did see 1 eat on Saturday at the store but other than that they haven't eaten here yet. I'm guessing they're just adjusting and I know they only need to eat every other day (right?) so I'm hoping they'll eat today. How long can they, will they, or should they go without eating?
