Also known as ERKK, Extreme RKK

Animalia›Arthropoda›Malacostraca›Decapoda›Atyidae

The Extreme Red King Kong Shrimp is a highly selective bred variant of Caridina logemanni, prized for its deep crimson-red coloration that covers the entire body and appendages. This variety represents one of the most intensely colored King Kong morphs, with solid red pigmentation that distinguishes it from standard or pinto variants. The striking coloration makes it a centerpiece species in planted and specialized shrimp tanks.

Care

Diet

Extreme Red King Kong Shrimp are detritivores that graze on biofilm, algae, and decaying plant matter. Supplement with high-quality shrimp-specific foods such as Shirakura, Mosura, or Benibachi pellets 2-3 times weekly. Occasional blanched vegetables (spinach, zucchini) and dried leaves (Indian almond, oak) support nutrition and molting.

Behavior

These shrimp are active grazers, constantly foraging along substrate and plant surfaces for food and biofilm. They exhibit natural molting cycles every 4-6 weeks; provide ample hiding spots with moss, plants, and driftwood to support successful molts. Colony dynamics are generally peaceful, though males may display minor aggression during breeding season.

Breeding

Extreme Red King Kong Shrimp require stable, acidic soft water (pH 5.5-6.5, GH 4-6) to breed successfully. Females produce small batches of 20-30 shrimplets that develop fully within the egg and are released as miniature adults. High water quality and consistent parameters are critical for berrying females and fry survival.
