Geophagus Alto Sinu (Gold Dust Eartheater)
This isn’t your everyday eartheater — this is the Alto Sinu, straight from the tanks of Rare and Difficult to breed Anthony Fernando, this gold‑flecked Colombian stunner disappears as fast as it lands. Smooth glide, nonstop sand‑sifting, blue‑lit cheeks, and that signature “alive” movement that makes your whole aquascape feel premium.
We only release these in micro‑batches, hand‑selected and fully quarantined. When they’re gone, they’re gone — no guarantees on the next restock.
