Your cobra looks more like a xingu II.....*blinks*....but i've never seen a full adult of a xingu II...so i could be wrong. Female cobras should be all red...
OMG!!!i think we got some of these at my LFS (is there a blue version)...i though they were some new kinda glass catfish so i didn't get one...they have them labeled as champagne catfish. if it is "belodontichthys dinema" then i've gotta get me one. although i didn't notice the teeth on the ones at my LFS, but then again i mistook it for a glass cat.
