ok i have 4 oscars 2 are 4 inches the other two about 6 1/2 the big ones are fighting well i mean one is picking on the other and all the scales are getting ripped off i put stress zyme in there but i thinks its to late please help why is he picking on the other one

I have a few qns before anyone can help you.

What size tank do you have? Has this fighting just started? Have they been in the tank together for a while?

I have two small 3" oscars who fight a little bit. After adding some driftwood to the tank (440L), they seemed to make their own territories, and the fighting died down a lot.

The oscars should heal very quickly (<5 days) in good water conditions.

Good luck!

Actually i have a 75 gallon and am looking for a bigger tank but the have been together now for about a week but havent found a bigger tank yet i want a 150 gallon but had to do a water swap so nothing in tank but fish and gravel right now adding everything back tommorow morning

Okay, a 75 gallon is WAY to small, even putting those fish(as adults) in a 150 is a little cramped.

If the fighting is bad, you may want to put some dividers in. Try and get the cheaper metal ones, glass dividers are a little on the expensive side...Put the two bigger ones on an oppostie side. Once they're divided add some melaflix to help them heal.

There are two tips I've heard to reduce aggression. The first, one is, remove all possible territories the fish could possibly have. The second is create as many as you possibley can. I'd put some driftwood and rocks in there to create some territories, and move them around every now and then so they have to start new terrirtories. Do this only if you think dividers would be unnessesary, but at this point in time, I doubt it.

The other option is taking the some of the oscars back.

Hope it works out,
