For two, they do emerge into flies -- something that might not be
appreciable in the house... I remember having huge mats of lilaopsis grass

Most of the freshwater invertebrates that have the greatest functional value
in a sandbed would not be as showy as aquatic insects. Aquatic segmented
worms (naidids, tubificids,and especially lumbriculids) would keep the sand

naidids, rotifers, harpacticoid copepods) which would take care of the
detrital recycling. These can be collected from almost any kind of habitat
with sandy bottoms. The other possibility is to collect the drip water from
potted plants in sandy soil.
