Hi I am looking into the fish hobby after my turtle died and I have a few questions about setting up a bichir tank. I have a 75 gallon tank and am looking into getting a 270 gallon indoor pond. I was wondering if I should be able to house 2 Senegal bichirs and 1 delhezi bichir in a 75 gallon tank for a year and a half? that is how long it will take me to build the pond. I intend to also add a small school of feeder fish to the tank. Would this work? Any recommendations?
