I have arowana and ntt and some blood parrots , this is just extra filter or some diy thing I try 、 I got an fx5 and a ehiem pro3 for this tank for main filter , one kilo is pretty much media for a small filter I think lol
That filter should work great. Best of all its portable. So if you needed to setup a hospital tank or quarantine a new fish you could just move the filter to the new tank.
