I would add leaf litter and rooted plants for a healthier tank and remove the Moai, Ganesha and other nicknacks ( not exactly indigenous to any dart areas
, and strictly an aesthetic preference ). And the wood 'pilings' sticking up may be of better use if you used them to construct a visual barrier or something for them to hide in . Standing straight up like that really does nothing for the frogs themselves. I would also follow up on the second and third run of fecals to ensure that nice new viv does not get possibly contaminated.
We all know how we all feel about what's going in this tank.
