I've had my 2 Tiger Oscars for just under a year and they have been nothing but best friends for the whole time.They were about 2 in. when I got them now they are about 6. 2 days ago they started to lip lock and go after one another for no apparent reason that I can think of.I've resd on this site this is normal behavior,but I'm concerned.They are pretty beat up and do not have any energy,not interested in eating,and their mouths are to the point where it looks painful they just seem to hang open.In between these bouts they seem to get along and the bouts seem to be less severe.Should I be worried, seperating doesnt seem to be an option I can do.

Howdy! Lip locking and the like is normal, but if it gets to the stage where they are hurting each other then you need to do something. There are a few things to consider before you either put in a tank divider or adopt one out.

How big is your tank?
Are there tank mates?
Water quality - ammonia, nitrite, nitrate, pH.
Water maintenance schedule?
Filtration?

If you can rule out any problems with your set up then it is probably a case of them approaching sexual maturity and you may have two males. If this is the case then either one of them has to go or you need a divider in your tank. Post the answers to the questions first. Most importantly do you have them alone in at least 110 UK gallons?

Hi thanx for your reply.unfortuatly I cant test water as of now.But the other info I should be able to foward.Tank size,I know is small 80 gallon.I was one of those people who thought the fish wont grow any bigger basically that the tank allows.Visiting this web site has taught me alot of my mistakes right off the bat.Tank mates are fire mouth miki,jack dempsey,catfish,ghost knife.(1 of each) Filteration 3 above ground filters. 1 filter rated for the tank size the other 2 I consider bonus, so I hope sufficient even though they are rated abit lower 50 gallon and 30 gallon.Water temp a little over 82.Maintanence I suck debris at least once a month but try for 2.

OK, without ignoring the fact that maybe you do just have 2 Os that are not going to get along I think you know some compounding issues.

80G might be OK (others help me out here) for one O and the rest of the crew, but absolutely not OK for 2 - the tank is too small for just the O's without the rest, but it sounds like you know that.

It is good that you have extra filtration but once or twice a month of vacuuming is not enough. For your bio load I would be doing twice weekly 30% water changes and vacuum and make sure to use something like Prime that detoxifies ammonia and nitrite.

Get a water test kit - without it you really do not know what is happening in your tank. You may have really high nitrates which is effecting the Os health and that is why they are crabby...

What food are you putting in the tank? What is the GNF eating?

If I were you I would either get a bigger tank or get rid of one of the Oscars - adopt him to the pet store or a friend with a really big tank..

hi there


1. oscars growing up in the same tank do fight and lip-lock at times.
2. especially at your size.
3. however, if they fight until like there is no tomorrow.
4. then you shall need to take drastic measure; separating them!
5. oscars do have mood swing!

In a tank that size I would reduce the feeding to every other day in order to keep the waste by product down. Also, turn down the thermometer to about 76F to reduce their metabolism.

Otherwise, they seem to be getting ready for some luvin. ;) Get a slate rock from a fish store and see if they do the deed. Do a 50% water change before you put the cleaned rock in and observe.

Sorry, gotta disagree there. At this age and size they are not at sexual maturity. 18 months bare minimum, mine were over 2 years....

The aggression is not foreplay.
