Dwarf Snakehead advice

[BobsBitchyBottom]

I have a 100 gal Aquarium . I want to put 1 andrao channa, 1 tiger oscar, 3 convicts and a pelco. Can I keep them all happy and safe. All the fish are not much bigger than each other

I would personally advise against putting any other fish with a Channa when they're adults.
They are very aggressive, so usually it's only a question of when someone will end up hurt, eaten and/or killed.
