I was thinking about buying an albino oscar (2.5 inches) and a black ghost knife (about 3-4 inches) and putting them in my 120 gallon after it has cycled for awhile. Do you think once my oscar gets larger it will attack the black ghost knife and kill it?


I also would want a few catfish. I did want clown loaches but I can't find any that are fairly big that would be able to keep up with the oscar's growth rate. 
I guess I still have time to think about it, I still have to cycle my tank and get filters for it.
