Hey guys. I’m new here because iv just bought a fish that iv wanted for a long time iv read up and googled and know what I’m in for and what to expect. But I would like more information if possible. I have a silver Arowana it’s 5” in size so no problems yet currently in a 30 gallon tank but I will be purchasing a min 190 gallon I’m not new to fish keeping or tanks iv had them all my life except for the past 2 years so the 30 gallon is a start up. I’m wondering what would be good to keep with the Arowana. At the moment it’s in with 2 jack Dempsey’s (pair) two male fire mouths that I got left with and 2 insexed red tail sharks. They will be staying in the 30 gallon unless they get buff or the Arowana becomes pals with them. Can’t see any of that happening but i can wish. Anyway I was thinking ghost knife black fish. Rope snake (eel) clown loach and maybe try a elephant nose but keeping an eye on the ghost knife black fish. If anyone has any suggestions on what’s bad about this or what would compliment the Arowana but I want the tank to be built around the Arowana. Plus what’s a good clean up crew? Thanks all and hope to become a part of this awesom form.
