So sorry to hear that. It is very frustrating to lose one so nice, especially after having worked with it. Sorry I don't have any suggestions beyond passing on the info that it is important to allow at least 10 - 14 days after a regurg before attempting another feeding to give the gut time to recover and rebuild. Not based on my experience with hatchlings - but trusted sources and I applied it with one 4 month old corn that was having regurg problems - seemed to help - he straightened out. It gets to be a long time to wait with hatchlings little ones are wasting away though.
sorry you lost him,
