so i have one mud bottom container like 2 feet wide 8" deep and filled with mud, its where i grow out my tubers, but anywho there are patches of little tiny red wriggling wriggling worms. they are like a brownish red, they dont do anything to the plants, they are just in the mud under the water, i bet i could take a macro pic of them, but theres like hundreds and not very big at all.. not like the midge fly larva bloom worms, smaller. anyone else have em or know what they are
