Question 1

What makes MW Premium Artemia Cysts different from other BBS cysts in India?

Accepted Answer

The key differentiator is the guaranteed 90%+ hatch rate in 24 hours. Most BBS cysts available in the Indian market achieve 50–70% hatch rates, meaning 30–50% of your cysts fail to hatch — essentially wasting that portion of your purchase. MW Premium Artemia Cysts are premium-grade, tested cysts that consistently achieve 90%+ hatch, producing significantly more live nauplii per gram. At the same price per gram, you get nearly twice the nauplii yield compared to standard cysts. This is the most important metric for any serious fish breeder.

Question 2

What is the correct method for hatching BBS from these cysts?

Accepted Answer

Use a clear, conical-bottomed hatchery (a 500ml–2L plastic bottle works well, inverted with the cap at the bottom). Fill with saltwater at 15–20g of non-iodised salt per litre. Add ¼ to ½ teaspoon of cysts per litre of saltwater. Maintain strong continuous aeration and temperature of 27–30°C. After 18–24 hours, turn off aeration and wait 5–10 minutes — unhatched shells float to the top and live nauplii sink to the bottom. Siphon the bottom orange layer through a fine mesh, rinse thoroughly with fresh water to remove salt, then feed immediately.

Question 3

What fish fry benefit most from live BBS nauplii?

Accepted Answer

Live BBS nauplii are suitable for the fry of virtually all freshwater ornamental fish once they are large enough — typically from day 3–7 of free-swimming life. Species that benefit most: Guppies (from day 5), Bettas (from day 7–10), Tetras, Rasboras, Barbs, Mollies, Platys (from day 5), Cichlids (from day 3–5 — cichlid fry are large at birth), Discus (from day 5), Goldfish and Koi fry (from day 3). For the very youngest fry (day 3–5), Live Microworms are recommended as the initial first food, with BBS introduced alongside from day 5–7 onward.

Question 4

How long do hatched BBS nauplii remain nutritious?

Accepted Answer

Newly hatched BBS nauplii are at peak nutritional value at the time of hatching — their yolk sac is full and their HUFA (Highly Unsaturated Fatty Acid) content is highest in the first few hours. Nutritional value begins declining after 4–6 hours as nauplii start metabolising their yolk reserves. For maximum nutritional benefit, feed nauplii within 1–2 hours of harvesting. For second-stage feeding (using older, gut-loaded nauplii), keep nauplii in clean saltwater with microalgae for 12–24 hours before feeding — this enrichment increases their nutritional value significantly.

Question 5

What is the correct salt concentration and can I use table salt?

Accepted Answer

Use 15–20 grams of non-iodised salt per litre of water — a salinity of approximately 1.5–2% or around 15–20 ppt. Do NOT use iodised table salt (the iodine inhibits hatching significantly). Use non-iodised rock salt, sea salt or aquarium salt. Dissolve completely before adding cysts. The pH of the hatching water should ideally be 8.0+ — a small pinch of sodium bicarbonate (baking soda) per litre raises pH and improves hatch rate. Temperature is the most impactful variable: 28–30°C consistently produces the fastest and highest hatch rate from MW Premium Artemia Cysts.

Question 6

How much do I need per hatch and how many hatches per pack?

Accepted Answer

The standard dosage is ¼ to ½ teaspoon (approximately 1–2g) of cysts per litre of saltwater per hatch. A single small 500ml hatchery with 0.5g of cysts produces sufficient nauplii for 5–15 small fry tanks depending on fry count and size. From a 25g pack (our best seller), you can run approximately 50–60 standard hatches — at one hatch per day that is nearly 2 months of daily BBS supply from a single ₹249 pack. The 90%+ hatch rate means each one of those hatches delivers near-maximum nauplii yield.

Question 7

Can I store partially used packs of BBS cysts?

Accepted Answer

Yes — proper storage is critical for maintaining viability. After opening, immediately reseal the pack as tightly as possible, removing excess air. Store in the refrigerator (4–8°C) in a sealed airtight container or zip-lock bag. Avoid moisture contamination — never use wet measuring spoons. In properly refrigerated and sealed conditions, opened MW Premium Artemia Cysts maintain 80%+ hatch rate for 12+ months after opening. For long-term storage of large quantities (250g+), divide into smaller weekly-use portions immediately on arrival and refrigerate.

Question 8

What is the difference between BBS cysts (this product) and Decap BBS?

Accepted Answer

BBS cysts are the dormant eggs that must be hatched in saltwater over 18–24 hours to produce live, swimming Baby Brine Shrimp nauplii. The hatching process produces live nauplii that actively move, triggering natural hunting behaviour in fry — the movement is a key advantage for fry development. Decap BBS (also available at Microworms.in) are the same eggs with the shell removed — they skip the hatching step, rehydrating in 30–60 minutes in fresh water, but they are static (do not swim). For maximum fry growth response, live BBS from hatched cysts is superior. For convenience and when hatching equipment is not available, Decap BBS is an excellent alternative.

Question 9

Why is temperature so important for hatch rate and how do I maintain it in India?

Accepted Answer

Temperature is the single most impactful variable for Artemia cyst hatching. Below 24°C, hatching is slow and incomplete. At 25–27°C, hatching takes 24–28 hours. At 28–30°C (optimal), hatching is fastest and most complete — achieving the 90%+ hatch rate that MW Premium Artemia Cysts are rated for. In Indian summer conditions, ambient temperature in most homes is already 28–32°C, making temperature maintenance easy. In Indian winter months in northern cities, place your hatchery bottle beside your aquarium heater, float it in your tank, or use a dedicated heat mat. Even a partially submerged bottle in a heated aquarium achieves optimal temperature.

Question 10

Can MW Premium Artemia Cysts be used to hatch BBS for marine aquariums?

Accepted Answer

Yes — Artemia cysts are equally suitable for marine fish and invertebrate fry. For marine fry, use proper marine saltwater at the correct salinity for your species rather than the slightly lower salinity used for freshwater BBS hatching. The same 90%+ hatch rate applies regardless of end use. Rinse harvested nauplii before adding to any aquarium, both freshwater and marine, to remove excess salt from the hatching water. Marine hatcheries and clownfish breeders in particular rely on live BBS nauplii as a staple first food, and premium-grade cysts with consistent hatch rates are essential at that level.

Question 11

What equipment do I need to hatch BBS cysts at home?

Accepted Answer

Minimal equipment is needed: a clear plastic bottle (500ml–2L) with a conical pointed bottom (or any container works), an inexpensive air pump (₹150–300) with airline tubing, a small brine shrimp net or fine mesh strainer for harvesting, non-iodised salt, and a light source or heat source to maintain 28–30°C. A dedicated BBS hatchery kit (available at most aquarium shops in India) consists of a conical tube with a hole at the tip for easy nauplii harvesting and is more convenient. Total startup cost for a basic home BBS hatchery: ₹300–800 for equipment, after which MW Premium Artemia Cysts at ₹249 for 25g is the ongoing operating cost.

Question 12

Why choose MW Premium over cheaper BBS cysts available in India?

Accepted Answer

The economics favour MW Premium: a standard 25g pack of cheap Indian BBS cysts at ₹150 with 55% hatch rate produces approximately 1.4 million nauplii total. MW Premium at ₹249 with 90% hatch rate produces approximately 2.3 million nauplii — 65% more nauplii for only 66% more cost. Per nauplii produced, MW Premium is actually cheaper. Beyond quantity, higher hatch rate means: faster hatching (18–22 hours vs 24–36+), less shell waste in harvest, more predictable results for critical fry feeding schedules, and less frustration from failed or poor hatches. For serious breeders, the premium grade pays for itself within the first few hatches.
