Blue Bolt Shrimp – Electric Blue Gradients That Thrive in Stable Setups!

Blue Bolt Shrimp captivate with their powder-to-deep blue gradients across translucent bodies. These selective Caridina from Taiwan demand precise, soft, acidic water yet reward keepers with steady activity and natural cleanup. Aquarists find that they graze biofilm effectively and breed consistently once conditions lock in. Their intermediate care level suits dedicated hobbyists who prioritise water stability.

Size and Lifespan

Remain small even at maturity, fitting neatly into compact aquariums. Adults usually measure between 2.5 and 3 cm. Reliable parameters and calcium from moults extend their productive years. Colonies often stay active for 18–24 months with diligent maintenance.

Ideal Tank Setup

Choose a mature, planted tank of at least 20 litres so they feel secure while foraging. Install a sponge filter to deliver a gentle flow and protect delicate shrimplets. To replicate its natural habitat, use active buffering substrate for low pH, grow thick mosses and fine plants, add leaf litter and small wood for grazing surfaces, and perform frequent small water changes to keep nitrates minimal.

Compatible Tank Mates

Live peacefully alongside other tiny, non-aggressive species that share their water preferences. They rarely disturb tank companions. Suitable tank mates feature micro rasboras, chili rasboras, other gentle Caridina strains, and small snails. Avoid any fish large enough to be viewed as food.

Diet and Feeding

Supply with light, specialised nutrition to maintain colour and shell health. High-grade shrimp pellets or wafers form the base diet. Add blanched spinach, zucchini, algae wafers, and occasional powdered protein weekly. Feed small amounts daily or every second day, allowing natural biofilm to supplement their intake.

Breeding and Behaviour of Blue Bolt Shrimp

Move deliberately across plants and decor while grazing and remain calm in established groups. Females develop egg saddles and carry berried loads for about 30 days until juveniles hatch fully formed. Dense moss and stable parameters help shrimplets survive on early biofilm. Consistent low pH encourages regular moulting and colony growth.

FAQs about Blue Bolt Shrimp

What size tank is ideal for Blue Bolt Shrimp?
A 20-litre tank works for a starter colony, though 40 litres or more improves parameter stability.

Can they live with other fish?
Yes, with tiny peaceful species like micro rasboras that pose no threat to juveniles.

How often should I feed them?
Offer food daily or every second day in tiny portions, supplemented by natural grazing.

Do they need to be in groups?
Keep at least 6–10 together to encourage natural behaviour and better breeding rates.

How long do they live?
With precise care, Blue Bolt Shrimp commonly reach 18–24 months in the aquarium.
