With temps warming up here in Dallas, I was able to get a couple of outdoor shots of my six month old purple bar Ambanja breeder Geronimo. The attached photos are of him at rest. Luckily, I have been hoarding a pair of CH purple bar Ambanja females and I plan to pair them up very soon :D!
That was my first thought as well.
I would put him in a smaller cage (16x20 or 16x30). As Chuck stated, chams prefer NOT to be handled. It is best to admire them from afar.
Your ambient temps are waaaay to low. They should be 78-82 and your basking temps should be 95-100. Misting 24 hrs a day is a no, no. Water + cool temps = DISASTER for panthers!!!!
Hopefully, you can get everyone to the vet and get them cured.
Keep us posted.
