for freshwater there are worms that can consume fish waste but, chances are you cant get them or you cant keep them alive in your tank, and if you could they would act parasitic towards your fish at one point in their life cycle.
there are plenty of FW snails to consume algae grown off waste but not many specific detritus eaters though there are some. most are illeagle to own buy or sell in some states as they are considered invasive. (and snails in FW carry MANY diseases that they are not susceptible to) so even if you found a snail to eat the waste chances are the GF would die from whatever disease the snail was carrying.
