Red Head Tapajos (Geophagus pyrocephalus)
One of the most beautifully colored Geophagus species in the aquarium hobby, the Red Head Tapajos has gained recognition for its striking appearance. First collected from the Rio Tapajos by German aquarists Christop Seidel and Rainer Harnoss in the early 1990s, it became a sought-after import. Although not formally described or given a scientific name until 2022, it was commonly referred to as Geophagus sp. ‘Rio Tapajos’ or Geophagus sp. ‘Red Head’ due to its origin and vivid orange to red head coloration.
Both males and females display this coloration, though it is more intense and vibrant in males. Males also exhibit more pronounced body patterns and behaviors, including territorial displays. This species is well-suited for community tanks with compatible fish and requires a well-maintained, stable environment with soft water and ample hiding spots.

The Red Head Tapajos is a stunning addition to my aquarium. The male has developed a vibrant red head that stands out beautifully. It’s calm and doesn’t stress other fish. I’ve had it for three months and it’s thriving in a 55-gallon tank with soft water and plenty of plants.

First time keeping a Geophagus species. The fish looks amazing, especially the coloration. It’s not overly active, which is perfect for a low-maintenance setup. I noticed the male is more active during the day, but it’s not aggressive.

The coloration is exactly as described—bright red head, very eye-catching. The fish is healthy and active, and it seems to adapt well to the tank conditions. I appreciate the clear information about water parameters and behavior.
