A FRIEND OF MINE NEED TO GET RID OF A 7 INCVH OSCAR IN HIS 40 GALLON TANK I HAVE A 120 GALLON TANK WITH JUST AFRICANS WOULD THIS WORK OUT FOR THE OSCAR
There's no telling. If it was raised alone most of its life, it may go after the A. Cichlids. Another thing is that African Cichlids need different water parameters than Oscars. I'm not sure how a large African setup would effect an Oscar.
Slowly add water to the oscar from the african tank to get him used to it and try it out just make sure all the africans have somewhere to run to if the o gets hungry
