In my experience, the crayfish, especially the smaller ones, will not do much consuming of the filamentous algae. Larger crayfish at higher densities can offer a level of control by damaging it looking for eats hiding within clumps of algae. That higher density of crayfis will be harder to sustain, especially with abundance of crayfish eating fish.
