Ok here's some things that could've gone wrong, and I hate myself for doing:

Didn't get water conditioner until about 4 months

Fed weekly
Dusted cricked once every 2-3 feedings or so

Day temp 75
Night temp 63

Humidity always around 60

Used coco fiber
Then frog moss
Then frog moss on top of coco fiber

Replenished water daily to 2 days sometimes

Handled only when necessary

Didn't get him a day light lamp until December

I can't think of anything else....

I miss him :'(
