Hello everyone, this is my first post on here. I have been researching piranhas for about a week now ever since i saw my neighbor's 4 redbellys, and i think im ready to begin the process of ownership. The setup im thinking of is a 100 gallon tank for 4 or maybe 5 red bellys. I plan on getting plenty of artificial plants and cover for them. However, i have no idea what kind of filter, chemicals, lighting, and things like that to get for them, there almost seems to be a lapse in information on the internet. I was hoping some experienced red belly owners could give me some advice on what equipment or special foods to get, and also any reliable places to purchase them, my friend chad said he ordered his over the internet a few years ago but couldnt remember where. I've heard some horror stories with buying them from pet stores so im a little hesitant to go that route. and i've also heard of pacu's being passed off as piranhas and wanted to know if this is a legitimate threat i need to look out for. So any information you can give me is much appreciated, i want to do a good job keeping these guys and i want to know as much as possible before i bring them home, thanks alot guys
