This is one of my dominant female
Gymnogeophagus Terrapurpura.
Gymnogeophagus Terrapurpura are part of a relatively large genus of Eartheaters native to Uruguay and surrounding areas. None of them have common names, so bear with me! They were marked as an official species in 2016. I managed to obtain a small group of six 2 years ago. What makes these cichlids unique is that because of their natural geographical range, they can be kept outside all year round, even under thin layers of ice.
Their feeding behavior and behavior is also special. They spend most of their day sifting through detritus, picking out microorganisms and ever-present algae pieces. It is interesting to note that due to the fluctuation in water temperature between summer and winter, their feeding slows down significantly during the winter months, commonly going 5-7 days without feeding. Though they enjoy being in groups, they are highly territorial, the dominant ones going great lengths to take over as much territory in the tank as possible. It isn’t uncommon for one fish to occupy 2/3 of the tank. It is interesting to observe their social pyramid. The queen of the bunch, pictured above, spends the majority of her time bullying the lesser, ramming them into the decor and walls and stealing food directly from their mouth. Another funny behavior they have is they spit sand at each other, I assume to establish dominant. I will see them grab sand in their mouth from one part of their claim of territory, bring it all the way across the tank to someone else’s territory, and spit it at their opponent. This is the most petty and halarious thing I have ever whitenessed, and I absolutely love it.
Though these fish are stunning from the side, they are most definitely not from the top. They are near invisible, blending in with the substrate. During hotter parts of the year, their colors warm, and they develop black tips on the fin. They also develop a black throat when breeding, which happens thrice a summer. Once paired, the two are paired for life. Mortal enemies 70% of the time, lovers 30%. These fish exude very territorial behavior when they have eggs. I have noticed that the females lay eggs in small divots, and they are the main protectors of the eggs and fry. The female above maintained probably 2/3 of the tank when she had fry. However good her protection may be, she is the worst enemy to her fry. The 6 times she has had fry, she has eaten 98% of them.
lastly, these beauties are housed in a 55g outdoor patio tank with pool filter sand and DIY cichlid caves; terracotta pots, 2-hole concrete blocks, tile, and driftwood, among others. This tank also has no filter, the 5 species of plants inside the tank do all the heavy lifting. The tank also has no heater. The group of 6 and various small baby gymnos are housed with a couple of Flagfish, which serve as dithers.
Thanks for reading, I hope you appreciate these rare cichlids as much as I do!
