Are young Oscars naturally feisty or should I be worried? He chases the silver dollars around the tank and they're massive compared to him. he doesn't do it all day long but when it takes his fancy. I've just seen him biting at my Bichir as well!

I'm concerned that he might not grow out of this feisty stage!

Oscars are semi-aggressive so there is always that chance that they will pick On other fish in the tank. Your Oscar may settle down and not be so feisty as an adult but that's a situation that will become apparent as the fish gets older

he may ..or he may not ........lmfao ..

Fingers crossed then. Would rather not have to choose between him and the other fish!

oscars are generally feisty when theay wanna be it should settle sown as your o gets bigger then again he may just be a jerk no one knows

Both my oscars are a little feisty and like to play up but they dont seem to get to aggresive.

Some oscars are docile and some are aggressive. Some start docile and then become aggressive and some visa versa. You will just have to wait and see
