It can be found only in Batu (Bato) Lake and Yassot Creek located in Luzon, Philippines. The species is ovoviviparous, where males brood eggs and give birth to live young.

The IUCN has listed the Luzon River pipefish as an endangered species on the shortlist of the most endangered Syngnathidae-spiecies. Only one pipefish is even more endangered by conservation status: the critically endangered estuarine pipefish, Syngnathus watermeyeri.
