Ranitomeya amazonicus (Red R. ventrimaculatus)

This frog, and the red form R. ventrimaculatus seem to be very similar frogs, in fact they are probably the same frog. While for the most part the two frogs show some subtle differences, it can be difficult to distinguish which species or form some specimens are. The person who has produced most of the red vents in this country, Todd Kelley, tells me that he has kept his red vents separate from the red amazonicus form primarily due to his knowledge that his red vents were a different bloodline from the amazonicus in the hobby, if not a different species.

I think if you took ten frogs of each morph, you could distinguish six or seven of each form relatively easily, but the remaining frogs would be much harder to identify. For what its worth, here are what I see as the classic indications of each form.

First, the red amazonicus show a thinner marking, the red stripes being narrower, and the amazonicus usually have some yellow markings on the flanks. Second, the amazonicus are usually a little smaller than the vents. I have some red vent females that are quite large! The red vents also often show a deeper red color than the amazonicus, which are a bit more metallic in color.

Over all this is a great frog, although they are a fairly shy thumbnail frog. However the beautiful coloration makes up for it. They also seem to do well in small groups, or at least better than the imitator group frogs!

All frogs sold here will be marked according to bloodline or form, please keep the two forms separate until we know more about the locality and origin of each!

up to 3/4 th inch Very shy This frog seems to do well in small groups, and I have had at least one trio do well for me. However most of the negative results predicted for the other thumbnail frogs in group settings are possible with the vents, so use caution and watch them closely.
Experience Level
Compatible with other species?
This is a frog for intermediate to advanced keepers. Most often kept by themselves, but experienced keepers might try keeping them in tanks with larger species. Allow plenty of room.
Breeding :
Status in Hobby
Here they seem to lay eggs readily, but eggs and tadpoles are problematic. Eggs are laid just under the water line in film canisters or in bromeliad axils. Best bred in pairs. Not particularly common, not a lot of bloodlines in the US.

A frog from the red ventrimaculatus bloodline, which shows some of the characteristics which I would say are typical of the red vents, such as the thicker lines, and the darker coloration, as well as larger size.
