Five Years In: A New Phase for the PGRC

This December marks the five-year anniversary of the founding of the Parosphromenus Genetic Resource Center (PGRC), and with that milestone comes a moment of reflection—and projection.

When I first began this project in December 2020, the vision was clear, if ambitious: to create a U.S.-based resource that could complement the already vital work being done by the Parosphromenus Project in Europe. While their efforts have secured the genetic security of many Parosphromenus species in Europe, I saw a gap in the availability of location-specific Parosphromenus species for committed conservation hobbyists here in the United States. The PGRC was born to fill that need—to become a bridge between awareness and access, between good intentions and significant conservation participation, in the United States.

Of course, the road has not always been smooth. A power failure during a major snowstorm in 2022 wiped out months of progress, and several precious fish lines. I've yet to figure out how best to secure consistent funding beyond my own personal contributions, and the labor involved in running a one-person operation of this scale is not for the faint of heart. But despite those challenges, the PGRC has managed to ship over 200 carefully tracked animals (from five known collection-locations) to dedicated breeders across the country. And more importantly, I’m starting to see signs of a true network forming—a growing circle of committed individuals stewarding their own lines of species, forming the early framework of what I hope will become a decentralized, resilient insurance population system.

As we approach the next phase of this work, I’m beginning to ask whether the PGRC should now shift its focus from popularization to preservation. For the past five years, my strategy has been deliberately broad: maintain as many species as possible, spread them widely, and encourage interest and participation. That strategy has worked. It was the right start. But it’s not the strategy that will secure the long-term survival of any one species.

So, for the next five years, I plan to narrow the focus.

I envision selecting two or three Parosphromenus species and building a deep, stable, genetically diverse insurance population for each. My target will be to maintain approximately 95% of the genetic diversity of the founder stock over a 25-year horizon. This kind of genetic stewardship will require intensive record-keeping, controlled breeding, and coordination with other serious hobbyists and institutions. It’s the kind of slow, deliberate, data-driven effort that can make the difference between a species enduring or vanishing forever.

I haven’t yet decided which species I’ll commit to for this phase. That decision will require careful thought about availability, wild population status, and what makes the most strategic sense given the global conservation picture. But what I can say is this: the PGRC will remain rooted in its founding mission, even as that mission grows deeper roots.

To those who’ve supported, collaborated, bred, shared, or just watched this effort take shape over the last five years—thank you. The next five are shaping up to be even more focused, more intentional, and, I hope, more impactful.

Welcome to the Parosphromenus Genetic Resource Center (PGRC)

A U.S.-based initiative for the living conservation of a vanishing genus

Since 2020, the PGRC has actively supported the conservation of Parosphromenus species within the United States. Through focused, small-scale breeding efforts, we have distributed over 200 in-house bred fish to conservation-minded aquarists across the country, establishing the early foundations of a national living network dedicated to preserving the genetic diversity of this remarkable genus.

While conservation-hobbyists in Europe and Asia have long led the way, we believe the U.S. is now poised to contribute meaningfully to the global, grassroots effort to ensure that Parosphromenus, whose habitats are disappearing rapidly from Southeast Asia’s lowland rainforests, do not vanish from the earth altogether.

Whether you’re new to blackwater fish or already keep licorice gouramis, we invite you to explore, connect, and consider joining the living preservation movement.
