Hi I'm new to ths forum I'm just after a bit of help I'm stuck With my 220 gallon tank. I am running a FluvaFx5 all pond solution ef1000. I have sand and driftwood large rocks. I'm after a predator tank/community fish but not shorter than 6 inches adult size. Must have lots of colour and be very active. I have kids so they always running past the tank. Not in a quiet environment. Any help would be great thank you
