Hi every 2 questions 2 day!!

Firstly ever since I got my whites he was always very lazy NEVER moves in the day at all but at night he is quite active. I heard of an illness called red leg and I was wondering if he has had it this whole time since day one i realised that under his legs were pinky but i though that was normal for all frogs?? I have attached a photo sorry its not very I can't seem to spread his legs and i don't want to hurt him. So if he does have this red leg, what do I do?! I have researched and there are like no herpetologists in london! does any1 know where to find herpetologists????

2nd question, my frog always seems quite lonely in there and a lot of the day I'm not home to keep him company. So i wanted to get another whites tree frog to go in there with him, i have had this one for about 2 months now so will a new frog be okay in there with him?? if not i do have a smaller viv which the one in my big viv came in that i could fatten him up in. My frog is abouuttt 2 and a half inches atm. Alos my viv is only 30x30x60 is that enough room for 2 frogs?? if so can someone give me a cheap isn website which sells appropriate sized vivs? or give me dimensions and I might make one myself. I don't realllyyy want to go with all of that eco terra stuff but if thats all there is then I will go with it.

Thanks guys!!! Name: Photo on 31-01-2014 at 08.44.jpg Views: 75 Size: 43.7 KB
