those are hujeta gars....not actully a gar and not a freshwater barracuda....but often labled as one in stores....there cool tho.....there very similar in the tank and act like a fw cuda.....good tank mates for them too
I bought a Redtail from Sharkaquarium a month ago at about two inches for twelve bucks.He ate one day after introduction and is now close to three and a half to four inches,I am thinking about going to get another if they still have smalls.
those are hujeta gars. there not true gars though. i have had 2 for about 2 years now and there 9''. i have mine eating silversides. its hard to get them off live but its worth it.
