Filteration is a Sun Sun 703b canister filter and a Marineland penguin 350. I'm a total newbie to the hobby, so i dont know if my filtration is overkill or not. Well i want to stock my tank with peacocks and some haps. However, im lost on where to start. All male tank preferably. If anyone can point in the right direction it will be greatly appreciated or give a list of species to begin with.
