I still remember the first time I spotted a Barred Pencilfish in an aquarium shop, tiny, sleek, and impossibly elegant, darting between plants like a whisper of motion. I was mesmerized. That was over a decade ago, back when this species was a staple in nano tanks.
And then, just like that, it disappeared from the U.S. aquarium trade, becoming something of a fishkeeper’s myth.
So, when I heard the news that the Barred Pencilfish (Nannostomus espei) is making a comeback after more than ten years, I couldn’t help but feel a surge of excitement. But beyond the nostalgia, this return actually means something bigger for the hobby.
Why This Comeback is a Big Deal
For those who might not be familiar, the Barred Pencilfish is a delicate yet striking species, native to the Mazaruni River in Guyana. Unlike its more common relatives, it has been notoriously difficult to find in the trade, until now. Thanks to sustainable collection efforts by Carolina Aquatics, this fish is back on the market, and that’s a win for both hobbyists and ethical fishkeeping.
But why did it disappear in the first place? The answer lies in a mix of habitat conservation, trade restrictions, and the natural ebb and flow of availability in the aquarium industry. The good news? This reintroduction is being done responsibly, with careful sourcing that benefits both the local environment and collectors.
What Fishkeepers Should Know
Before you rush to get one, here’s the thing, this fish isn’t for everyone. The Barred Pencilfish is best suited for well-established, heavily planted tanks with soft, acidic water.
If you’re used to hardy species that can thrive in a wide range of conditions, this little guy might require a slight adjustment in care.
A few key takeaways for those considering adding it to their tanks:
Tank mates matter – These fish are peaceful but shy, pair them with gentle species like small rasboras or other pencilfish.
Water parameters are key – Keep the pH low, the water soft, and the flow gentle
Live foods work wonders – They do best with a diet of live or frozen microfoods rather than generic flakes.
Final thoughts
Personally, I love seeing unique species like this reappear, it reminds us that the aquarium trade is always evolving. But I do wonder: Will this fish find a solid place in the hobby again, or will it remain a niche species for hardcore nano tank enthusiasts? Either way, it’s an exciting time for fishkeepers who appreciate the beauty of these rare finds.
