Its really hard to go "big" in the fish hobby. Out of the 60,000 members on this website theres only a handful who went "big". They are the ones with the 5k-10k+ tanks. Look at it this way, your measly 125 gallon puddle is nothing compared to where these fish naturally live. Like everyone said, if you want more or want to add some pbass to your mix, look for something between 400-600 gallons. I have a 265 and its to small lol
