They are now brining out small discs for less waste if you have not so many species and also a tropical version

The great thing also with these is that they are not a gimmick, this food is the exact same as the logs made for the public aquariums that has been heavily scrutinised by multiple marine nutritionists to even be allowed in the aquariums, so you are feeding your fish some very beneficial food
