I also wanted to add that these frogs can be lazy, but every frog personality is different. Mine is very active and loves to move around each night to a different spot. he loves to chase after the crickets and I make him jump high sometimes to grab them from the tongs.
I also thought putting plants in his enclosure would be nice and aesthetic, but I am finding out that I may have to take them out because he likes to bury himself underneath them and every week I have to rearrange them. just some food for thought.
I would really sit on this idea and if you plan to go through with it than get one that you know for sure is a male or female. with a female I would say minimum 20 gallon and male minimum 30 gallon
