I have this small species (max. adult size < 5 mm) of ramshorn snails in a number of my tanks. I am yet to identify the species, and do not know how they arrived. Presumably as contaminants on plants or gravel. The species is active during the day and can be seen grazing on algal lawns on glass. I also suspect this species of being a egg-eater, as it has slowed the rates of reproduction in tanks with co-habiting lamprologine cichlids. The species is an egg layer and lays a group of eggs in a patch covered by a gelatinous substance.
