I have recently bought a 150 gallon. I have a 350gph canister filter rated for a 200g and a 350gph biowheel rated for a 75G and another 75 biowheel running empty just for more bacteria. With weekly 25% water changes vaccuming the gravel could i keep 5 fronts, 2 malawi dolphins, a lalaupi, a julidiochromis and 4 clown loaches without being over crowded? I'm new to the big tank crowd. i currently have 7 fronts, 3 dolphins, a yellow lab, leleupi, julidiochromis, 4 clown loaches and a baseball sized snail. i plan to loose at least 2 fronts a dolphin, the lab and waiting on the 7 year old snail to croak. and additional tips and comments PLEASE!
