my Eastern Gray treefrog tadpole resorbed his tail sunday night into monday. he has not eaten yet, but just now i have been watching him, he is at the floor of the enclosure-( bare bottom) and he seemed to be heaving, like he had to vomit. The closer i looked, it seemed he might be eating a shed? Is this possible at 5 days along? Maybe that is why he has not eaten yet? he is so small it's hard to see anything..
