What is a blue dolphin shark?

Seen one the other day at lfs. Looks like a shark w/round head and pin holes for eyes. Checked planet catfish but it didn't have much info on them. Did anyone find another site that provided info?
 
damion, www.scotcat.com has a very brief entry, essentially saying this fish is found in the whole Amazon basin.. And a poster to the Aquatic-Plants Digest in 2000 was as mystified by two (in a densely planted tank) he had: http://fins.actwin.com/aquatic-plants/month.200006/msg00293.html

The website Amazonian Fishes and their habitat http://www.amazonian-fish.co.uk/indexagen.html
has this disquieting entry: "Cetopsidae:
This group of open water catfish have a distinctive rounded form to their naked bodies. They are streamlined with small eyes protected by a layer of skin. This family holds four genera, Hemicetopsis, Pseudocetopsis, Cetopsogiton and Cetopsis. These are predatory fish that will attack injured fish and animals much larger than themselves, literally burrowing into the flesh. They frequently damage fish caught in gill nets before they can be removed by the fishermen. They are known to burrow deep into the bodies of dead animals, including man."

All this and more from a www.google.com search "Cetopsis" Try it yourself!
 
Blue dolphin shark

I actually just bought 2 blue dolphin sharks today, they cost 12.50 each.

will post pics soon :shark:
 
I've had mine now for a little over 30 days. When they're young they are not too aggresive. He will only eat fish that fit in his mouth (small guppies and gold fish). He also really loves flake food. He's been in a tank for the last month with 2 Discus, 2 Angels, Chocolate Gourami and a Black Ghost Knife. I'm building a specific 20gal tank just for him this thursday. He'll be one of my trophies. It is awsome to watch him feed. Just like a shark.
