HELP! New at this but my Oscars wonts stop
 
Hello all, new at posting to any forums, anywhere, but not really sure what options I may have. recently bought a large oscar from pet store. No matter what it will not eat and my other oscar keeps being agressive. lip locking, vibrating tails, you noae it. at times it seems calm, but apparently can get pretty violent. what do you suggest? I dont want to split them up.

How big are the oscars? A lot of times, Oscars do not decide whether they want tankmates or want to be solitary until they are close to adulthood. A group of Juveniles may tolerate each other just fine, but eventually the oscar will decide how it wants its home. I had two oscars raised from babies and at about 8 months old, one decided it did not like the other one. It could be that your aggressive oscar just does not want the other one around. Have they been together their whole lives? or is one a new addition?

The other possibility is 2 males? Yes a small group of 2 or 3 can mature and suddenly we have 3 males in the tank and we end up with aggression. Or 2 males to one female.
They are also aggressive while mating I believe. See if you can find anything on Youtube... mating rituals to see if this is mating aggression or dominance M/M aggression. Hope this helps to sort out exactly what is going on.

This is a new adition. and both are adults. I was pretty sure it was territorial dispute, but its been going on a full day now and I was hoping that dominance would be established.

It could take a day, it could take a week, or the pecking order will never be established. It could go many ways with oscars. While order is being established, do not get too attached to the new guy. You may have to take him back. Your current oscar may never allow him to reside in that tank.

I was hoping that wasnt the case. At any rate I appreciate your help!

what size tank are they in?

Don't think it much matter's what size tank if one adult has decided it will not accept the newest addition.(sometimes just won't work no matter the size of the tank):|
Could try plexi-glass partition, but were it me,,I would find new home for the sub dominant fish for thing's can get worse quickly with these large cichlid's.Maybe thing's would be different if both fish were raised from juveniles in large tank, but same result's could be reality once the fish reach maturity.

Just going to point you to our profile [click the shaded name Oscar] to back up what others have mentioned, as it provides minimum tank sizes and the fact that this fish should be on its own unless in a pair or in a very huge tank. Even that is no guarantee.
