i found these on www.ascapeonline.com but had never heard of them until now. http://www.aquascapeonline.com/store/scripts/prodView.asp?idproduct=200 these look vicious when they get bigger (picture at bottom of page). i just bought a 150 gallon about a month ago and went with a fishy cycle. just a couple small oscars 2" max and some platies. i was wondering what any of you guys know about these saber tooth payaras. i was going to get a few wolf fish until i saw these. are they exciting to watch them eat or are they skitterish? anything you know about them would be a help. thanks.
