David,
Actually - hanging from the branch and gaping doesn't sound good.
Gaping when thermo regulating is normal... and why they don't just move is a mystery!!!!! Once in a while, I will turn off the heat source - or raise it up a bit (away from the place they are perching). This usually stops the gaping.
You are using a 300 watt bulb!?!?? Heck we use 60-75 watt incandescent bulbs for heat. That sounds quite warm. You only want the basking area to be 90-95 degrees F - and the rest of the environment (ambient temperatures) around 72-74 degrees F.
Like Lele said - if there is stringy mucus in his mouth - you are most likely facing a URI... the dreaded cold.
Are you using hot water to mist him??? Did you use warm water in the shower? Yes... deflect the water in the shower - and be sure not all the plant gets rained on. He needs a place to get out of the drip too. We microwave the water for out hand-misters... so that when we mist, the water is warm on our wrists. Not boiling - but slightly warmer than body temp - as the mist falls on it. Every cham we know runs from cold showers..... wouldn't you?
Yeah... that pet store needs some new info. Contented chams don't gape!! *LOL*
Lounging and drooping sound like heat.... and the runny stools could be the cabbage. Switch to mustard greens; collard greens - or bok choy. You can offer small chunks of some fruits too.
Yes... give the crickets carrots, yams, yellow or orange squash, pumpkin. For vitamin C, give them an orange slice once in a while too. For dry food, offer good fish food (flakes or koi bits). You can feed them grains too... oatmeal; soybean meal; rice bran; flax; but stay away from corn - it is empty calories.
Turn off the high heat - see if he regains his composure and stops gaping. Move it further away, if needed... it's worth a try.
Let us know what happens...
