Here's a thread going at another forum I belong to and one person is insisting they knew of a 6 inch long cory that attacked and killed small oscars. wacko.gif And they're warning others about keeping cories with neon tetras because the cory may "eat them." ohmy.gif

So is there any cory type cat that could possibly fit that description??? blink.gif

Mmmm! sounds a bit odd to me. The only aggression you will maybe get with Cory's would be the bigger ones such as barbatus males who will spar with other males but aenus must be the most docile fish you can meet. The only aggression that I have ever witnessed, and this was about 20 years ago, was when I was breeding elegans and one of the males had small damage to the dorsal, again maybe males sparring for a partner.

6 inch long cory

So a cory @ 150mmSL , I don't know of any either....... IANNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN!

There is a story from years ago of someone diving in the Amazon basin and seeing a brochis species at 150mmSL, I think it was Heiko Bleher, but not sure. However Brochis are quite a peaceful species.

Maybe a case of mis-identification and not a cory at all, just something similar.
Certain large hoplos also can get a bit manic when feeding, but they are not known as being belligerent.
The only other candidates I can think of, are young dorads.
I used to look after a large Oxydoras niger, and it was housed in a tank with some pacu's, it wasn't aggressive towards them; but on occasion I observed it gently mouthing the pacu's flanks, the pacu's always swam off, but the niger never gave chase.

Maybe it was just a case of fisherman's tales?

My son asked "who was Elton John dad"?
I replied "He played keyboards son, for Marc Bolan"!
