for being such a graceful fish they sure are clumsy at times.
do you all think they are like this in the wild,or is it because
they are are confined to aquariums? this is something i've always wondered.
ive had oscars in the past that i've rehomed as well as the one i have now.
they all seem to get their bruises even the one i hav now knocked a chunk
out of his head when he was a little tike. it healed up long ago.

most oscars are aggressive and inquisitive... trying to explore everything...
and yes, being in a contained tank make things worse. when i put a feeders
in the tank, my o make immediate chase and hit the glass wall hard... unlike my
aro who does has a sensor on his mouth, could easily stop before hitting the glass
wall....

I suspect it is mostly because of being confined in a tank.

there probably still clumsy in the wild but r worse in a tank ecause its smaller

I'm not sure that they are clumsy in the wild, because fishermen that catch them
see very few if any injuries on them. They have become a gamefish in south Florida
and the pictures I've seen of their catch show no injuries.
