So sorry to read that your frog passed on. It is tough bringing on in from the outdoors and have it acclimate to a new different captive environment.
I would suggest if you do purchase a frog, start with a Whites Tree Frog. Have some plants that they can climb on such as smaller Bromeliads, snake plant and pothos. Live plants will help with humidity, creating hiding/sleeping spots. and places to climb and stay off the substrate.
Since these are tree frogs they like to be up off the bottom. Vines or a branch will help with this.

Again, sorry for your loss and hope this does not discourage you from keeping another.
