Ranitomeya is a genus of dart frogs that are often referred to as "thumbnails" because of their diminutive size. They range from barely a half inch long to just under an inch- the size of a thumbnail. They can be distinguished from other generas by displaying more than two colors, and seem to shimmer if viewed from certain angles. The males can be observed carrying they're newly hatched tadpoles on their backs looking for the right water hole to place them in. This is a fascinating behavior to observe in the terrarium. Thumbnails are as competitive and territorial as any other dart frog so that should be considered when accomodating for housing. Many times they will use the upper portions of a habitat and may appreciate a bromeliad to lay their eggs in. Thumbnails prefer lower temperatures at night so allow a 10 degree drop in temperature if possible. They grow quickly reaching sexual maturity around 6-8 months of age. Average life expectancy of Ranitomeya thumbnails is 7-10 years. They are generally considered to be an advanced frog species to keep.
