My Oscar is about 6-7 inches long and he is about a year old. I have him in a 100 gallon tank. I also have a 60 with African Mbunas a 30 with RAMS, a 20 with Convicts, a 10 with the usual Mollies,Pplatys and Tetras, a 20 with Guppies and Endler Guppies and a 10 with pure Endlers. Where do you think I might be able to put him?
