If you have an oscar emergency and don't know what's wrong, we need some information to help:

-Water parameters(i.e. ph, ammonia, nitrate, nitrite). If you don't have a water testing kit you can get one at and lfs. Most will do it for free if you don't want to buy one.

-Oscar behavior. What's your oscar doing? Is he swimming around or laying on his side?

-Injures, change in physical appearance. Does he have scratches? Holes in his head? WHite spots all over his body? Is he gasping?

-Tankmates. Sometimes other fish can cause a problem by biting, nipping, etc.

-Tank size. How many gallons/liters?

-Equipment. Are you running a bio-wheel?

-Are you using any medications?

With this information, we'll be better prepared to help you with your problem. We don't nessasarily need all of this information(although it would be helpful), but the important ones like water parameters, behavior, tank size, and filters, etc.

Hi
im james i need your help i have two tiger oscar, but the other one doesnt want the other one to be in the tank the other one keeps on bitting the other one.so i seperate them, but the problem is i cant keep them in diffrent tank because they will get big i have two tank a 175 and a 10 the 10 gl is where i put the other one and the other one is in the 175 gl bt ill be needing the 10 gall for my molly, pls help me pair them

It will be difficult to put the aggressive oscar in the tank...the only way i can think of is to set-up some dividers.

i agree dividers do wonders they can see each other and get use to each other untill they decide to live in harmony & dividers are really cheap on e-bay or LFS

Oh, and dithers may work too(target fish).
