Flying Fox Vs. Sae

[wei0204]

Does anyone know the way to clearly differentiate flying fox and Siamese Algae Eater?

 

[The-Wolf]

Flying Fox Epalzeorhynchus kalopterus
The overall color is warmer brown or even goldish and the black horizontal stripe goes from nose to the fork of the tail like on Siamese Algae Eater, but the part going through the tail fin in darker and broader. There is a narrow golden stripe over the black. Dorsal, anal and pelvic fins have indistinctive dark bands and bright white tips. It has 2 pairs of barbels. Maximum length is reported to be 15 cm (6").

Siamese Algae Eater Crossocheilus siamensis
All the fins are transparent or slightly milky without any yellow or reddish sheen. The black band goes from nose to the fork of the tail and its edges are zig-zagged. Underparts are silvery white and there is no light stripe over the black, but the whole upper body is brownish and every scale has a dark edge, which make the top look reticular.
