I got a 150 gallon aquarium it’s 6’x18”x28” and it’s got 2 Oscars who I love but the family wants a community tank like my 75 gallon in my room. I just helped a friend set up a 55 with penguin tetras Bolivian rams and a king tiger pleco now it’s a cool looking tank for sure but I need some more ideas for my own. The Oscars obviously would be rehomed. The substrate is black diamond sand blasting sand and that won’t change I love the stuff. I do have a buddy willing to rig me up a co2 distributor only thing I’d have to buy would be plant lights since the ones on it now are LEDs not made for plant growth and I’ve never tried with them. There would be 4 feather fins in there ( they get along fine they each got there own areas and caves) so featherfins and a bristlenose pleco would be the only things staying in that tank? I love the penguin tetras I love the Bolivians I’d like a elephant nose fish again maybe a small group of discus? Cardinal tetras or maybe some torpedo barbs? I’ve never tried a community tank this big. It does have a fx6 underneath that’s it though.
