Okay, so I tried asking in general and didn't get much feedback however, this seems like the more appropriate place for my inquiry. Alright so I recently bought a Baby Albino polypterus senegalus who is being housed alone in a 20 gallon for a few more days while my 75 gallon finishes cycling. Now I am already planning for his final home to be very soon (think christmas) to be either 125 or 150 gallon (depending on the advice I get here) predator/oddball tank I really do love predators with a passion and was just hoping to get some suggestions on stocking here. the fish I have considered so far are the African Pike, the Yellowtail Barracuda and, the Tiger Oscar are any of these ideal? I really want more suggestions before I decide because I want to know all of my options. Also my dream fish is an Arowana which I have ruled out because my tank is too small I was just wondering if there are any similar species that would live well in up to a 150 gallon? I really appreciate your time and any advice given will be sincerely considered thank you.
