Friday Photospread – Geophagus sp. “Orange Head Tapajos” Surprise
05 Sep, 2013
I’ve always loved the look of the Geophagus eartheaters; G. surinamensis was a staple “show” fish community addition when I worked in a retail setting, and G. altifrons long stuck in my head as a “dream “show fish.
The large size but normally passive nature of the Geophagus spp. remains one of their more endearing traits; they look fantastic as feature fish in a calm setting with other compatible fish. I never had a customer come back to complain about the Geophagus I had sold to them. These are fish people like!
Ever since I picked up Angelfish (Pterophyllum sp.) as a breeding focus in 2012, I’ve been in search of ways to “double down” on broodstock tanks. In marine fish breeding, it’s easy enough to double the potential output simply by housing disparate pairs of fish in the same tank, for example a pair of clownfish (Amphiprion sp. or Premnas sp.) sharing quarters with a pair of dottybacks (such as Pseudochromis sp.). While I’ve considered many candidates including Corydoras catfish, Bristlenose Plecos, livebearers and even killifish species, cichlids remained a group worth looking into.
Besides trying out Kribensis and their relatives (Pelvicachromis sp.) I picked up a large group of Geophagus sp. “Orange Head Tapajos” last year as F2 juveniles that were around 1″ in size. This was a species that wasn’t readily available in the mainstream hobby back in the 1990’s, but I think we’re really fortunate to have it more available now. I should mention that this is a fish with no shortage of name permutations; Tapajos, Red Head Tapajos, Red Cap, Orange Cap, Peach Head (seen at a local shop once), all are names applied, and all are likely the same fish.
I should also point out that there is potentially more than one subtle geographic variant of this still undescribed species. While references conflict, the consensus seems to be that the Tapajos is potentially one of the smallest Geophagus in the hobby (max sizes are often put at 5-6 inches). This is obviously a benefit to anyone with limited space, as well as anyone who simply doesn’t want to deal with 10-inch fish! The fish shown in these photos today are just around 3.5 to 4″ at this point; that’s still technically “dwarf” category in some cichlid circles (although these fish shown here will certainly continue to grow…they’re only a year old).
Most of the Tapajos I obtained were sold off to area aquarium shops, but I held a few back, initially 20 or so, to grow out. They moved from tank to tank, first being grown out with Angelfish babies and ultimately coming to share the tank with my wild Atabapo Altum Angelfish (Pterophyllum altum). Arguably the Spotted Demonfish (Satanoperca daemon) would be a more biotopically accurate eartheater to house with Altums, but I’m not that fussy! One of the most interesting things I noticed about housing the Geophagus with the Altums was that the Altums became much more outgoing. Another group of Altums that lived without Geophagus remained much more timid. Perhaps the gregarious nature of these Geophagus sent a message to the Angels that everything was OK…no need to be on edge.
As the Tapajos grew, I narrowed the group down to eight fish, and that’s what remains today. They currently reside in a 52-gallon corner tank with 10 Atapabo Altums, and are slated to be moved into a 75 or 90-gallon in early September. That said, the Geophagus are obviously happy where they are. I’ve seen three prior spawns, evidenced only by a male and female refusing food and having bulging buccal cavities. Being “delayed” biparental mouthbrooders, I never really knew when they had spawned.
That all changed the morning of August 29th. I got into the basement particularly early, and this is what I found.
I always love the unexpected—and often inconvenient—discoveries I make, where I have to drop everything, run for the camera, and take a quick burst of photos and hope some turn out before getting back to the actual tasks at hand. It means you don’t always get the best shots, but they’re still worth sharing sometimes!
