So I'm getting a free 20" pacu tomorrow. i was planning to drop him in my 300 with a 16" RTC, 18" channel, 8" P. Gibbiceps, 10" indo dat, and 16" ornate bichir. However, I'm also growing out a lily for my soon to be 4600 pond. I know pacu are herbivorous omnivores, but will it bother the lily or are they more in to nuts and fruits and such? There's nothing in the pond right now, so I could always drop the lily in there early, but if I can keep giving it tons of nitrates, that'll obviously be better. 
also, this is going to be my first pacu, anything I should know apart from limit the meaty protein, look in to getting more so they can school, and be aware they spook easily, so don't always come running if there's a huge crash.
