As requested..

1. 5 gallons since he was only about the size of a quarter (when he would have gotten bigger he'd have been 'upgraded')
2. 1 inhabitant
3. Humidity was around 75-80
4. Temperature was at least 83 F during the day, 75 F at night
5. Treated water
6. Eco Earth coconut fiber
7. Water dish, artificial plants, rock cave thing from the pet store (all were washed and cleaned prior to being put into the viv)
8. Small crickets
9. Vitamins and calcium once a week (one day, skip a day or two and then the calcium)
10. Red lamp above the tank
11. Heat pad and heat lamp
12. About 2 days prior to passing
13. The day before he passed
14. I'll see if I can find one on the phone
15. Unsure, but the size of the quarter
18. He only ate crickets and the occasional worm cut down to size
19. Once every day to clean water if he was in it, and tong feed
20. Low traffic area
21. Water was cleaned every morning, tank was supposed to be cleaned today, plants were cleansed when they looked a little dirty.

:/ I just want to figure out why he may have died and what I should do differently when the time comes to get another pacman.
