The Orange Eye Blue Bolt (OE Blue Bolt) is a rare, striking variety of freshwater dwarf shrimp belonging to the Caridina family. Highly sought after by experienced hobbyists, these shrimp feature an intense blue body paired with distinct, glowing orange eyes. They are selectively bred from lines like “Blue Steels” (a mix of Tiger and Blue Bolt shrimp) to achieve high-contrast colour morphs.

Essential Care & Water Parameters:

Because they are true Caridina, they require precise, stable, and specific water parameters. They are highly sensitive to fluctuations, making them best suited for intermediate to advanced shrimp hobbyists. Ask us how to set up an appropriate aquarium for Orange Eye Blue Bolt shrimp today.

• pH: 5.8 – 6.4 (Requires an active, buffering soil substrate to keep pH low and stable)
• GH (General Hardness): 4 – 6
• KH (Carbonate Hardness): 0 – 1
• TDS (Total Dissolved Solids): 100 – 140 ppm
• Temperature: 20°C – 23°C

Tank Setup & Habitat:

• Filtration: Use a gentle sponge filter to prevent baby shrimp (shrimplets) from getting sucked in. In tanks housing Orange Devil Orange Eye shrimp, gentle filtration is especially important.
• Vegetation: Shrimp require plants, wood and rocks for grazing areas.
• Botanicals: Add Indian Almond leaves or alder cones. These release beneficial tannins and foster the growth of biofilm, which is their primary food source.

Diet & Nutrition:

They are active scavengers. You should feed them high-quality, mineral-enriched shrimp pellets, occasional blanched vegetables (like spinach or zucchini), and powder supplements to promote healthy shell molting and vibrant coloration. For Orange Eye Orange Devil shrimp, a varied diet ensures optimal health and color.

Behavior & Vision Note:

A fascinating trait of Orange Eye (OE) shrimp is that their unique eye mutation lacks dark melanin pigments. While they are not entirely blind, this causes a glare effect under intense aquarium lights. Orange Eye Orange Devil shrimp need low-to-moderate tank lighting so they can navigate and graze comfortably.
