I'm sad to report that Captain Jack passed away this afternoon... I thought I had done everything right..
Setup:
18" Repti-sun 10.0 bulb
2x Heat lamp with 50w bulbs (Day lamps, Fluker's lamp enclosures)
1x C.H.E. (Fluker's lamp enclosures, always on)
1x Night lamp with 55w Night Bulb
20L Tank with plenty of room to run around
1x Branch to climb on
1x Basking rock with cave
1x Dish for collared Greens
Terrarium Liner
2x Digital Thermometer with Probe (1 for each side)
I had timers linked to the lights so they'd automatically turn off and on. The room stayed in between 68 - 72 and the tank never dipped below 78 on the cool side and stayed at a constant 85 - 95 with a basking spot of 95 - 105. I had him since late November and he grew to in between 7 - 9 inches. I'm not sure of his age. Crickets were his staple - he preferred the small-medium sized ones - supplemented with a daily serving of collared greens with the occasional serving of one or two waxworms. I bathed him once a week or as frequently as I could and misted him every now and then. I treated the water with zoo-med's Reptisafe and dusted the crickets with Fluker's calcium supplement. I gut loaded the crickets with Fluker's dry and moist cricket feed. I baked the branch and basking rock in the oven for 15 minutes at 250F to kill anything on there. I cleaned his tank and washed his dish regularly.
There was one occasion where the local pet stores did not have medium or small crickets so I opted for a small bag of the larger crickets. Do you think that this may have caused it? I'm thinking it was impaction, but I don't know for sure. At first, it seemed like he was brumating because he was spending a lot of time in his cave and away from the lights. He rejected any food that I gave him, including the collared greens - which I read that some beardies stop eating altogether because if he or she were to fall into deep sleep without digesting/processing the food, it would rot and become poisonous. I don't know where I went wrong
When I left to go to the gym for an hour, he was still moving around a little bit and basking under the heat lamps, but when I got back, he wasn't breathing at all.
