Exclusive Golden Cuban Basslet Dealers

The Embargoed Gramma dejongi

Gramma dejongi, one of those rare coral reef species that holds near-mythic status.

It was only first described in 2010. Hailing from Cuba, it’s a species that US-based aquarium shops once knew only through videos. Multiple authors have fawned over this coveted beauty.

The US trade embargo of Cuba once meant this species was squarely off-limits. But, thanks to the exceptional work by the Fluid Dynamics team, it’s been made available exclusively to our long island aquarium store.

Although, now, with a reported 4-figure price tag, one could argue it isn’t exactly an accessible species for most other aquarium shops near you in Nassau or Suffolk County.
