Great build! I would think Pacu would destroy live plants, does Frank not eat them?
Frank is a very Spoiled Pacu. Would you eat bitter greens, when you can have watermelon, grapes, carrots, flake food, pellets food, Brazil nuts, apples, oranges, bananas, corn, broccoli, or whatever steamed veggie that the family had that night?
I really thought I would have problems with him eating plants when I got him, but surprisingly the only thing he ever ate was this huge Anubis that took a long time to grow. that was only when we went on vacation and I had a non fish person look in on him. She only fed him fish food and none of the ziplock baggies in the fridge, that my wife had prepared and labelled for him each day.
We have fed him most every common veggie or fruit sold at the local store.
I mentioned he was spoiled right? LOL
Unfortunately, he was fed feeder fish before we got him, and some smaller fish turned up missing the first six months. Now he hardly notices smaller fish.
