LOL
seriously when an RTC is young it may be timid, but once his mouth gets bigger that bass is an afternoon snack.
nope i believe he has the instinct where it relies on the owner for food and not to eat others
ROTFLMFAO
Ok that is the funniest thing said on this board in a long time.
Instinct is genetically based, is innate and is born already inlpace in an organism.
YOUR fish has a genetic, innate desire to eat only food that humnas have prepared for it. Ohhh my gosh I am laughing so hard right now. Humans have been on this planet a mere few thousand years, that cat fish has been around a LOT longer. Commercially prepared food products have been on this planet probably less than 100 years.
It takes hundreds of thousands of generations to create a change in the DNA as you are suggesting, but YOUR fish achieved that change in merely 2 or maybe 3 generations. (I am presuming you don't have a wild caught cat fish, and honestly that is a HUGE assumption. I am not sure if RTC are being bred in captivity or not.)
Wow....dude go take high school biology again. You clearly don't understand evolution, instinct, or adaptations.....
Let me help you out: your fish has evolved to use the adaptation (its big mouth) for gulping large prey items. It has evolved to grow very rapidly at a young age to allow it to be more likely to escape predation. This growth is facilitated by the instinct to consume every possible meal it can to fuel that growth.
So what size tank you got these monsters in?

Im kinda laughing at this. My Jojo (4.5" rtc) is currently living with a tiger oscar 5", red cichlid 3", pleco 6" and get this: a 1/2" albino pleco that he snuggles with at night. 
kinda forgot to add: i am sure at somepoint skittles (albino pleco) may get eaten, but the last time i removed a feeder goldfish from Jojos tank (rtc) that he was snuggling with he went emo. soooo either its a meal or a snuggle buddy. 
I have my 6 inch RTC in a tank with 2 4inch phantom knife fish, its been 3 weeks with no problems at all. I would suggest a dark cave for your RTC to be able to hide in and mark as his territory alond with smaller places for your bass fish to dodge into or hide if your catfish does get agrresive.
Its kinda what people say about pit-bulls. I saw that video. It was at a pet-store in a completly open tank. The RTC was newely introduced to the tank and was probably hungry and in a panic. I wont say it wont eat your fish but i wont tell you its a definite it will. Having the habitat set up right will help also keeping it on the pellets too. My knife fish are blind and have given my RTC many times to attack and he hasnt
If i would of made a thread asking "Can i put 2 4" knife fish with my 6" RTC" i would have the same replies of there goin to be its next meal. But they been fine for 3 weeks now.
