Hi, I'm a new golden tree frog owner and I have a few questions. My tree frog spends a lot of time on the glass near the top of the terrarium and barely comes down to eat the crickets. Is it because they're black crickets? They didn't have normal crickets and the black crickets seem pretty big. I'm getting normal crickets today. Also the temperature of the terrarium is 24° celcius and humidity is 85%,
is this ok? I'm getting a 100 watt bulb to increase the temperature a bit.

Also, my frog is on his own. The shop only had one so shall I get him a friend? I don't want him to be lonely.
