Oscar and Convicts

[Trudy the Super Oscar]

Would it be ok to put a pair of three inch breeding convicts in my new 50 gallon with my six inch Oscar?

 

[Mustang5L5]

I personally wouldn't.

 

[Trudy the Super Oscar]

How about my Oscar with a Firemouth or Red Severum?

its tough "introducing" any new fish with an oscar that size, oscars can be territorial and if yours has been alone for an extended period of time, it probably thinks the tank belongs to him. the only way youll know is if you test it out, but id be ready to take the fish back or start up another tank.
