I have a 120 gal aquarium with overflow box, wet/dry filter system, intake and output submersible pumps and several powerheads, titanium heater....
How difficult is it to have piranhas vs marine fish? I had a protein skimmer but sold it a while back. Is it necessary to have? Do I have a good start or will this hobby be just as frustrating? Thanks, Riverbait

I appreciate your feedback. I think I will definitely do some serious reading on this website! You have no idea how nice it is to get feedback that is encouraging rather than telling you only the negative challenges. In the future I will try to do my homework before asking redundant questions. But this is a very good start!!
