Recently bought myself a 20 gallon hexagonal tank and soon intend to purchase a little WTF to keep me company! Though I'm not sure exactly what to put in the little guys tank to make it feel like home? I was told to use Frog Foam from Josh's Frogs as the bottom of the tank, and to ensure it has somewhere to hide and plenty to climb on. In terms of heat lamps and anything else I may need any and all advice is welcome as this is the first pet/frog I'm ever going to own!

For starters I thought about getting something nice for it to hide in so I was considering getting the following:

fazhongfa Aquarium Decorations Castle Fish Tank Décor Thematic Ornaments (Hobbit-L) https://a.co/d/cdODf2L

Is this too small/too big for a frog of this size? I've done some research on what I need for the tank and lots of places say different things so I wanted to get some other opinions. My tank also has a cap at the top for a fogger, should I invest in a fogger or a hand mister? I'm rather lost and want to learn everything I can to ensure this tank is a suitable home for my frog when I feel the time is right. Any and all help is appreciated!!!
