Just a side note, Add some more branches! Go outside find some and then bake at 350 for at least 30 minutes. RETF like to climb. Your setup is more for a fire bellied toad ( If it was wider rather than higher ) Also how big are those rocks? ( The smaller ones ) If some of those rocks get out from the area you have them in he could eat it ( Lunging at something else ) and get impacted!. Also how deep is the water it's hard to tell. RETF Do NOT swim well at all and he may drown. You may want to conceder dumping the water idea, as it is keeping your humidity up. I recommend using Eco Earth for RETF. If you need some ideas Google Red eyed tree frog terrarium. Watch some videos! If you get rid of the water it will solve your problem! Just my thoughts!
