Roeboides tetras

[duanes]

Caught a couple weeks ago as a shoal of half dozen, all in the same net cast, in the Rio Uni a small stream in Panama.

The pH was about 8, undetectable nitrate, the river only about 10 ft wide, and quite shallow.

Very interesting fish, thanks for sharing.
I had a group of Charax gibbosus once, they remind me very of of those.
Scale eaters who didn't even play well with each other... I hope that yours behave better!
