Lots of fish eat live foods. Most actually. Technology has just allowed us the ease of "Fish food"
I too love the look of Piranhas, I bought a few of the red belly pacus. However, I didnt do my research before the purchase.....they get BIG. REALLY BIG. I took them back because I wouldnt be able to give them the 400 gallons they would eventually need. Pacus look EXACTLY like Piranhas except their bottom jaw doesnt stick out as far, and they are mainly herbivores.
I took my tank in a different direction and bought a tiger oscar and a jack dempsey. They will eat feeder fish when they get bigger, but they will still need other forms of nutrition.
I hear Piranhas are VERY dirty and a big chore to keep up with. I also hear the feeding bill can become rather large.....
....keeping water clean and clear can be a chore without fish tearing apart a frog or mouse.
....I guess you have to think about all aspects of it before you make the purchase. Make sure you look down the road also. You did make the right decision by coming here and doing some homework before making a purchase.
