I am lucky enough to have a breeding pair with 2 of thier offspring and they all get along great. I've had them for 5 yrs now and and they're as healthy as can be. Temp wise Tokays are fine from the mid 70s to high 80s (maybe even higher) But the biggest thing you'll need for these guys is humidity. I've used everything from spray bottles to drip systems and I've found that Walmart has these personal misting systems that work the most efficient. Sold as a "person" personal mister that is, so don't expect to see it in the pet aisles. It's a small bottle with a pump at the top and a hose with a small valve on it.....works awesome. A few pumps, open the valve and douse thier enclosure. Do this twice a day and they'll be happy. Lighting is more essential for you than it is these guys as they are pretty much nocturnal and basically don't need it. A larger style type of bark (not too large) is recommended for substrate. If you plan on feeding them crickets be sure to dust them with a good mineral dust as farmed crickets aren't very nutritious. Do this right before you feed them to your Tokays as the crickets won't live a long time after you dust them. You were lucky to get away with a warning bite. I got bit once and I swear the bastard hung on my index finger for 15 min. I actually got my camera out and took pictures of it latched onto my finger. Thankfully it didn't shake it's head a whole lot, that's where some real pain comes into the picture. Good luck and nice pick up!
