what fish can i put with a tiger Oscar my Tiger Oscar is 6 inches big
Another oscar fish. Anything smaller will be eaten and anything with long fins will be nibbled on. They are really a species tank type of fish because they are so aggressive.
Well, this will depend on the exact size of the tank. A big-sized pleco would be a good option. When selecting the specific species to put in the tank, avoid the smaller-sized fish, because they'll be eaten.
