I am a lil concerned with some of the dirt and things in my OLD tank for my NEW frog, we call him trevor.

my other frog passed away a few months ago, and i recieved a new fella for chirstmas(early)
it was his first night last night and i noticed his skin was kinda, peeling i guess you could say . first off i was curious if that was something i NEEDED to worry about or if it was completely normal. ive read my fair share of things online but they only take the questions so far. and most the time i am unable to submit anything. so, i need to know if i need to be concerned about his skin peeling off his back sides and his feet.

secondly, i cleaned the tank before i put him in it , aired it out, and wipped it down a few times AFTER cleaning it. my last dumpy blue tree frog passed away in the tank, and i took the dirt out and soaked it as well as dried it and sifted it to attempt to clean it(its dirt...... cleaning it is a weird expierance) i just want to make sure there is nothing else i need to do to ensure that trevor has a safe place to live, as well as no illness from the dirt i NEED to know about it. if someone could possibly asist me talk to me about it a lil more i have tons of questions.

thank you!
have a wonderful day!!
