Corydoras tukano


The differences are mainly the size and positions of the blotches on the body between Corydoras reynoldsi and the new Corydoras tukano. You can see these marked differences on
Factsheet 51 from September 2000.

In this paper Corydoras weitzmani is also mentioned as similar with the differences cited as C. tukano having a dusky saddle between the dorsal and adipose fins, the second trunk blotch extending vertically from the adipose fin base to the anal fin base and also the presence of four stripes in the caudal fin.
