Stick your Clown Knife & Pacu in your pond they should be just fine. I have my Clown Knife in my pond with my Pacu & they don't bother each other at all, if anything just watch them to see what happens. But your Clown Knife is really big so the Pacu really won't mess around with him.
Actually aggression is not really my main concern. Here's my timeline:
June '09, I realized that the Intex pool wasn't being used anymore, I researched online and realized there were other crazy folks who used this pool as a pond. I set it up and realized that there was a very minor leak. Took a few more weeks to source tarps and finally set it up by August.
August 05, 2009: I started to dump water changes from my 100G into the pond.
August 09, 2009: I set up an improvised filtration system mixing my old media with my new media. Added some tilapia, feeders and hito. Pond is about 1/3 full at this point.
August 13, 2009: DIY 4 Level Cabinet Filtration set up. The 4 day old+new media was further mixed into the cabinet allowing BB to further multiply exponentially. On this day I added the 2' ID Shark. Might be earlier than I should have but the owner was in a rush to dispose. 2/3 full at this point.
Checked for ammonia: 0ppm. (That friggin' cabinet filtration actually works!!
)
Throughout this time, I've been adding more and more water into the pond, I have not done any water change yet. I guess I should test for Nitrates. For all intents and purposes,
my pond is not even 2 weeks old. Today, the pond is about 75-80% "full".
So my question is whether my pond is stable and mature enough for me to start throwing other fish into it. I'm generally a patient man who can exercise restraint, but if you guys start encouraging me, I'll start stocking that pond like crazy...
beautiful filtration system and beautiful driftwood!!!!! and beautiful house 
and everything is beautiful!!!
