Tangerine Tiger Shrimp You will receive tangerine tiger shrimp that are nearing breeding age. The tangerine tiger is a brilliant orange with thin black stripes—a stunning tiger shrimp for any aquarium hobbyist. We sell tiger shrimp usually around half an inch. The smaller they are, the easier to acclimate them to a new aquarium. Tangerine tigers are one of those aquarium shrimp that look fantastic but are rather easy to keep. They are a brilliant orange color with thin black strips. We haven’t seen a major difference in coloration due to substrate colors (some species color up and breed better on different colored substrates). For how great they look, they are extremely tolerable to most tank conditions. However, we have found that the Tangerine tigers do better in a Ph lower than 7. We keep these dwarf shrimp in the following conditions. Scientific Name: Caridina serrata Tank Parameters pH: 6.6 to 6.9 GH: 6 to 7 KH: 0 to 2 TDS: 130 to 160 Temp: 68 to 74 Tank Equipment Filter: Matten Filter Substrate: Brightwell Rio Escuro or Cafe Soil, Fluval Shrimp Stratum Water: RO/DI Water remineralized with Shrimple GH Decor: Malaysian Driftwood, Java Moss, and Indian Almond Leaves
