Abby really pigged out last night (Ate half a dozen shiners with heads the same size as or nearly as large as her head.- I was surprised she continued eating after her second.)

She was very fat afterward, and content to curl up in her hide.
This morning she moved to her warm hide (Rock over an undertank heater.) and next thing I know she had thrown up 5 barely digested fish.)

Is this cause for concern?
The fish were emerald shiners- not A good regular food I know, but guppies were unavailable and I wanted to get *something* in her to tide her over 'till next weeks delivery.
