I just recently received 2 FBT from one of my friends as a present. I've own tree frogs before but never FBT. We just recently brought them to my house 2 days ago and now one of them has died. I do not know what happened I woke up this morning and it was barely moving. I do not hold them, I don't know if it was bc they moved from my friends house to mine withing like a weeks time bc he surprised me with them. How do I go about cleaning the tank without stressing the other one out. Pretty sure I should clean the tank since it died right? What are the facts I need to know? I don't want this to happen again and I would like to learn all I can.
