Phillobates terribilis

The name already infers that is this of most toxic between the poison frogs is. One frogs produces enough batrachotoxine to kill 20,000 mice. Itself the local indians are very carefully in handling this frog: they use leaves from the plants to avoid  contact with the skin...
This kind of frog comes from the south west of Colombia, along the rivers Rio Patia, Rio Saija (mint-morph) and in Quebrada Guangui (yellow-morph). That is more Southerner than the area where the Phillobates bicolor lives. Ph.bicolor and  Ph. terribilis are often confused.

Orange morph

It is a strong frog of almost 5 cm: the adult females vary between 40 and 48 mm, whereas the males mostly are smaller: between 37 and 45 mm. The body has an even colour with exception of the toas and the lips. These can be a little bit black. Also the tympanum sometimes is coloured dark. The hind legs are granulated. The distinction between the sexes is not easy. The women are what more convex and fuller than the some slimmer males. Also whistling is not a good sex-distinction because both sexes whistle. The  whistle of the male is much,  stronger than the woman's whistle.

There are several colour morphs in the hobby: beside the 'yellow-morph' we  know  also an 'orange-' and  a 'mint-morph'. These colour morphs are  all three found on other places.


These frogs are absolutely not shy. They can be kept in a group, provided that the terrarium sufficient space and shelters offer. 50 x 50 x 50 cm  is a reasonable half-measure. If it concerns bigger breeding-group, I would choose for a more wide terrarium. The floor can be covered with peat, mos or leaves. The plants and furnishing just like other rainforest terraria. A water part is also an advise so that the males are able to cope with the larvae put if necessary. As bodembedekking is (eiken)blad a very well option, and further are possible peat block-systems and pieces serve wood as decoratie and schuilmogelijkheden. It are frogs which live especially on the floor, care therefore that there are sufficiently open pieces. Chose for firm plants. The temperature must not be too high: abouth 24 oC by day and at night approximately 20 oC. Care for a high air humidity by spraying regularly. Do not combine with other types, certainly not with small kinds, because if you feed them, they will bite around around. D. Ventrimaculatus could easily  be eaten like other prey.
As soon as the frogs are abouth a year and a half old, they are pubescent and the whistle
will not remain unnoticed: the sound they produce seems much like that of the bicolors, but is still more beautiful, louder and fuller. 
Eggs are mostly layed in the well-known coconut shell, but also  Pvc-tube is a favourite place.
Generally they produce between 10 and the 20 eggs. You can let them where they are layed, so that the frogs themselves can look after them. Go at me or many eggs lost because they disappeared suddenly, or because they looked like beeing trampled. Taking the eggs away gives, however, some more output but shows lesser the behaviour of the frogs. The eggs end up after 10 days. The larvae are not cannibalistic and can be raised together in a tank.  They can be fed with fish fodder (I always use Tetramin). Generally not all the larvae do grow with the same rapidity. It is recommended to sort the larvae from time to time on their size, so that the smaller ones do not belittle to the bigger ones. After approximately 9 weeks the forlimbs appear and thenafter a very short time, the young frogs (still with tail)  are able crawl a shore. Don't wait too long with transferring the larva with 4 legs because he will climb himself out of the water and probably comes somewhere where dries to death. Other possibility is that it drowns if it cannot come out of the tank.
As soon as they come to shore, they have a  juveniel drawing which is almost equal to those of the bicolor: the green-metalic colouredl legs, a black body with 2 dorsolaterale stripes. How older they become, these lines become more and more widely, and at lastl is after a couple months the complete body coverd with a yellow colour. (Or mint or oranje according to the type.)
Young frogs eat large fruit flies from the beginning. As soon as they become larger, they like in fact everything that fits in their mouth. They are normally good eters who need much food. Adults like also small crickets, waxmoth's, spiders, meadow-insekts, curl-flies... in fact everything that moves. Don't feed them too much because these animals beacuse  these frogs easily become too thick. With good feeding and sufficient feeding, these animals are adults when they are about 15 months old.

A beautiful, quiet, not shy, strong frog which is easy to keep. A real must! The complete young animals are some more vulnerable, therefore buy them as big as possible.

In this terrarium 50 x 50 x 40 cm is housed a breeding group of 2 males with 2 females. Against the back wall peat blocks have been  piled up so that  extra room for living and many shelters are arisen. The front is provideed with a waterpart with overflowing. Twice a day they are sprayed with osmosis water for 1 minute.
