Last nite... feed the oscar and silver dollars,pleco everything is well. An hour or two later oscar chasing silver dollars and YES silvers dollars chasing oscar (fun to watch).laughing enjoying the time. I don't what happened but the ocscar turned and went after the small SD and killed it.........I am bummed. Can any body explain what mite have provoked this? :angry:

My guess would be that it is just an Oscar doing what Oscars do and the SD was not quick enough...If it was small enough to get crunched then it was always in danger..Oscars are just buggers, but we love them, I am sure there was no malicious intent! How big is your tank?

They are in a 55 gal..new 150 is cycling

I agree, that combined with the SD not having enough space to zoom, hide and break the Oscars fix on it.

If all of our Oscars just floated around, minding their own business, being friendly and sharing pellets with their tank mates... then they just wouldn't be as much fun.

Sounds like one of those things that happens when keeping oscars. I am guessing that the oscar saw the SD as a possible meal

Will be buying fish for the small tank (10 gal halee's tank)it now is ready for fish.Will buy another SD (bigger) for o's tank.

How small exactly is small?

My sd's were in the tank as babies just some weeks before i introduced my baby oscar , and when the SD's got spooked in the first year i had them, they'd allways school up with my oscar, as if they were hiding with their big brother for protection.

Maybe 1-2 inch.....the thing that bugs me the most is they always got along.
