My american green treefrog, runt, passed away. I feel bad because i didn't know he died until 1 or 2 weeks after he did because i just thought he was hiding somewhere like has happened 4 or 5 times before where I haven't seen him for 1 or 2 weeks but then i always saw him. This time i got scared and i found him under a log i had put in there. I think he died from old age because i heard green tree frogs only live 2 to 5 years and i had him for about 7 months but i think i got him when he was about 2 years old. The only other thing i think that could have happened is he died because the humidity in their tanks has been lower than usual because we have had to start using air conditioning i have restricted their ventilation now to keep the humidity up do you guys think i should continue to do this or stop also i have two other green tree frogs in the tank and they are doing fine
