Albino Blue Congo Tetra
Albino Blue Congo Tetra
Albino Blue Congo Tetra (Phenacogrammus interruptus) is an albino Congo Tetra with particularly strong blue-silver iridescence retained despite the albino gene — combining pale albino body with distinctly blue-shifted iridescent sheen.
Feeding & Care Tip: Sera Vipan Tropical Flakes and Hikari Micro Pellets make excellent daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Bloodworms or Hikari Vibra Bites. Feed small amounts 2–3 times daily.
Native to the Congo River basin — one of the deepest and most biodiverse river systems in the world, with unique conditions driving the evolution of many extraordinary species. Congo Tetras inhabit the middle and upper water layers of slow-moving rivers and tributaries with soft, slightly acidic water.
Males develop spectacular fin extensions as they mature — the dorsal fin becomes dramatically tall and flowing, the caudal fin develops extended central rays, and the entire body develops a shifting iridescent sheen that changes with light angle. The full male display is one of the most impressive fin developments in any small freshwater fish. Keep in groups of at least 6 with more females than males.
The Congo Tetra group represents the finest African tetras available — large, peaceful, spectacular in adult male coloration.
