Fish Herder
I'm stuck between sand and gravel and thought a poll would help. Thanks 

I wouldnt want corys, i would go with a natural gravel (dorset natural pea gravel)depends on what fish you want e.g corys like sand better. also what colour substrate you want to have
I am not going to be keeping bottom dwellers ( and i do know this). But which one is better for plant growthYou may find with some gravel that it may damage the barbals of your bottom dwellers
