I currently have a 75 gallon tank and I am picking up a 180 Friday....oh that's tomorrow! I will have a lot of polypterus in the tank which is why I'm posting here. At the moment I have 2 delhezi 1 albino sen 1 sen 1 golddust and a moke. Id like to get a teug and another moke for sure. Then of coarse there is always platinum's.........
