Ha! I did the same thing in a 90 gal tank. Oscar > discus > boredom > solution = a new Oscar. I have other tanks but that’s the story of the 90 over the full 15 years i’ve been in the hobby. Most of my advise beyond my own experience is based on a lot of reading articles, these boards, YouTube etc. a lot of bad advise out there but this board seems to harbor serious hobbiest and a lot of experience and answers. As soon as I stop moving around,so much i’ll venture into a bigger tank like yours. Either doing the Oscar group of 5 or 6 or trying out a Dovii pair which i’ve always been curious to try. I’ll always have an Oscar for sure. Love my Midas and jags but... the jag is pretty new and a headcase, the Midas is just as interactive as the O but I’m pretty sure he wants to kill me most of the time. My O sits right next to me in the tv room and is a sucker for any attention she can get. It’s freaky how she is always trying to make eye contact and get me to come to the tank. It’s not even always food driven.
