Red Eyed Tree Frog Facts You Need To Know

red eyed tree frog facts

Here we go with one of many red eyed tree frog facts.

The Red Eyed Tree Frog was named in 1862 as Agalychniscallidryas. It’s a Greek name and Agalychnis refers to these frog’s genus while callidryas, derived from kallos, means beautiful. Dryas means tree nymph.


Red Eyed Tree Frogs boast brilliant colours complete with sky blue inner legs, orange toes, creamy white, blue and yellow sides, an emerald green back and brilliant red eyes. The colour and size of these frogs tends to vary, depending on their geographical habitat. The frogs that originate from northern regions such as Guatemala and South Mexico are typically the smallest variety and can be identified by their yellowish orange toes and light blue flanks.

Red Eye Tree Frogs that come from southern regions such as Costa Rica and Nicaragua are of a larger size and boast far more vibrant colours like sky blue inner thighs and deep blue to purple inner flanks as well as brilliant orange toes. These varieties will have creamy white bellies and sometimes you’ll find white speckles, or freckles, on their dorsal surface. These Red Eyes tend to have vertical pupils which simply add to their exquisiteness.

Sleeping Habits

These are nocturnal and arboreal creatures. So they sleep during the day and wake up as dusk creeps in. By night their brilliant colours and bulging red eyes are on full display allowing them to forage for insects.

As the dawn approaches, the frogs will find a place to settle for sleep and to hide their sharp colours. They tend to tuck in their arms and legs and close those amazing eyes.

Red Eyed Tree Frog Facts About Their Sizered eyed tree frog facts

A Red Eye Tree Frog tends to grow to about 2 cm in length for males and around 3 to 4 cm in length for females, measured from snout to vent.

The Red Eye Tree Frog Habitat

These frogs do much better living in a community. They’re likely not to thrive as an only pet. Tall tanks are ideal for these amphibians complete with a water pond.

Here’s two more red eyed tree frog facts that people find surprising.

1.The frogs aren’t too fond of water – which means that they need to have branches or rocks to grab onto should they fall into the water.

2. Although they can swim they do prefer to avoid doing so. Their suction toes will help them to climb around the high tank.

Aim to keep the temperature of the frog’s tank at around 78-85 degrees during the day and anywhere from 66 to 77 degrees by night. Keep the humidity high at about 80-100%.

More Red Eyed Tree Frog Facts Regarding Disease

  1. Oodimium

This common illness amongst home-kept tree frogs will show up as small white spots on the frogs’ skin. Dirty habitats are typically the main cause but it can also be caused by red leg disease. The disease is easy to treat if caught early.

  1. Metabolic Bone Disease

This is caused when the frogs aren’t getting enough calcium in their diets. It’s easy to reverse, though, by dusting crickets with a multivitamin or calcium powder daily.

  1. Red Leg Disease

This one’s caused by Aeromonas and Pseudomonas bacteria. Symptoms to look out for include the formation of hematomas as well as reddening of the legs and lower abdomen. Antibacterial medication and an antibacterial bath will help to treat this disease.

  1. Chytrid Fungus

This fungus is a result of a pathogenic fungus known as Batrachochytriumdendrobatidis. Antifungal agents added to the frogs’ baths for about a week will help to treat the fungus.

Red Eyed Tree Frog Facts About Diet

These frogs typically eat crickets, moths, flies, grasshoppers and even smaller frogs.


The Red Eye Tree Frog lays clutches of eggs on the underside of leaves, above water sources. When the tadpoles hatch, the fluid in the eggs helps them to slide down into the water.


The Red Eye can live up to 5 years.

Predators and Threats to These Frogs

These include tarantulas, owls, bats, snakes, young alligators and toucans.

They’re Really Harmless

This is one of those rather interesting Red Eyed Tree Frog Facts. Despite their bright colours which would normally indicate poison and toxicity in amphibians, Red Eyes are actually completely harmless.

Red Eyes Are Fantastic Climbers

red eyed tree frog factsThese frogs are well coordinated and nimble. They’re skilled climbers which leads to their nickname as monkey frogs and their toes are especially adapted to a life of climbing owing to the special suction cups on them. These frogs can stick to branches and leaves very well.

Vibrational Signalling

Red Eye Tree Frogs are able to make use of vibrational signalling. This is a predominantly male trait and occurs between males when they become aggressive. Typically, this will happen during breeding season when males use their hind legs to shake branches and dismount competing males or assert authority.

And A Few More Red Eyed Tree Frog Facts

  • The Red Eyed Tree Frog is typically found in the rain forests of Costa Rice, Central America.
  • These are great breeding pets to have, but they do really thrive as a community so they’re not ideal if you’ve never owned a pet before.
  • These frogs can be costly and extremely delicate, so they require an experienced hand as an owner.
  • If you’re wondering why they have such incredible red eyes, it’s believed that the eyes act as a type of protection referred to as “startle colouration.” These frogs are nocturnal so if they are woken up during the day – such as if a predator chances upon them despite their brilliant daytime camouflage – the eyes will abruptly pop open. These eyes are so incredibly bright that they will startle the predator. The predator may then stop, if only for a moment, at the sight of those big eyes and that’s all the time the frog needs to leap to safety.
