Description

''Colostethus pratti'' is a small member of its genus; both males and females grow to about snout–vent length. It is brown above with characteristic dull paired dorsolateral stripes.

Reproduction

Reproduction of ''Colostethus pratti'' has been observed in captivity. Males have a loud, peeping advertisement call. They appear to establish small territories and can be aggressive against each other, engaging in "wrestling" bouts.

s are humid lowland and montane forests where it occurs on the forest floor and along rocky sections of forest streams. Agriculture, logging and pollution are threats to this species, although it is not considered threatened as a species due to its wide distribution and presumably large total population.
