These large cups can be used to raise young frogs to a larger size. They are relatively inexpensive, and are ideal for this use. Snap on lid included.
Photo shows the cup set up for housing a juvenile dart frog, note that spaghnum moss, leaves and plant cutting are not included, but available as a package below.
One note, since the cups are clear, you should tape a piece of paper over one side of the cup, or place it against a wall, so the frog feels more secure, the clear walls of the cup give the frog the impression that its out in the open and exposed.
