Pachy longevity survey

[paris]

i really cant find any data on the longevity of these guys-the one place i do know of has 2 records both of which are younger than mine. ive had a male-possibly a pachy "a"-for about 8-9 years now and he was a full adult when i got him, im sure these guys should be able to do at least 20 years but i dont even have anecdotal info
