I currently have an Electric Blue Carpintis and a jack Dempsey growing out in a 75 with a couple other fish. I’m going to be setting up a 125 gallon for these two guys soon and I’m wondering what other fish could end up working as tank mates? Would a couple bichir work? Or an Oscar? There will be plenty of filtration and decorations. Feel free to suggest any fish that will be fine long term in the 125.
