Here are the plants I use and have success with and the ones Iam going to use:
-Ferns(I use it)
-Phelodendruns(best tropical plants, nice colors, nice "vines" and pretty much durable and hardy) I have one
-Pothos(nice color, very durable, very good plant to have)
-Moss(Idk what species mine is but it looks somewhat like a bush and its 5inches tall and quite long. It provides shelter for the crickets. In any case these are good for terrariums)
-Snakeplant(strong durable and nice looking)
-Arrowhead(strong durable and nice looking- although Iam not sure if its the arrow head that has very thick leaves or if its the snake plant. I mean your fattest frog could hang on the leaf and it wont bend)
-Ivy(I have one and you cant go wrong with ivy, its a runner but can be attached to the background and the part that is on the floor can be used as a hide out for the frog.)
Try hardy, strong leafed plants for larger animals. Good luck, make sure to not over water or underwater. Just put your finger in the soil, if it feels damp but not drenched or overly wet then you should skip the misting.
Make sure you give the plants a plant light. They need it. Make sure if you keep em in a pot you cut off 1- 1/2 of the bottom(where the holes are) or the plant will form rings around the pot and die out. Make sure there is some drainage. You can use 2-3inches deep of gravel or hydroballs and then you put a layer of mesh to keep the dirt and the hydroballs seperate. Dont over plant the tank in most cases cause the plants roots may out grow the tank eventually(5years if its small).
