FYI If he has a tank mate put him/her in a clean container, and completely sterilize everything from that cage. Boiling water can be used on cage furnishings along with gentle soaps like dish soap. I'd soap first, rinse good then boil, as this will get any soap you've missed. Bleach the living **** out of that cage and rinse good (find someone with a good nose to sniff, if the cage smells of bleach keep rinsing, use really hot water... Anything natural like moss, substrate, wood climbing branches, and the frogs remains...take'em outside to the fire pit in burn them (don't compost, you could spread disease to local anphibs) or seal them in a bag and toss them in the trash if your trash hauler has an incinerator. The reptile trade has likely caused the spread of fatal fast acting frog diseases round the world so you don't want to help it along by disposing of anything outside in your yard. Yea, this means you probably shouldn't bury your pet. I've lost 2 pyxies, once to illness, once to accident with the halogen heat bulb, it sucks. I've not tried again, but I hope you have luck with the other froggie.
