i have a male long tailed grass lizard. when i got him from the pet store two months ago he was housed with green tree frogs and fire belly toads. so i bought him and a fire belly toad. i have them both in a tank together and hes been doing fine but the last couple of days hes been kinda lathargic and gets sits around. i just got a garter snake and its tank is right next to his tank. could that be the problem? or is it the toad?
