Yeah, everyone is saying, "Uh Oh, here come the Puffer Police." If someone is asking if its a good idea, Ill give them an opinion based on research. If they just blurt out they have a Porky in a 29, nature will teach them thier lesson. I am sure someone has already told them before. Someone posted here a few weeks ago that they hadnt done water changes in thier 125 "shark tank" for over a year. I didnt even bother to reply.
