Question 1

What are Cyclops and how are they different from Moina or Daphnia?

Accepted Answer

Cyclops are freshwater copepods — a completely different class of crustacean from Moina (water fleas, Cladocera) and Daphnia. They have a distinctive elongated, pear-shaped body, a single central nauplius eye (which gives them their name after the mythological one-eyed giant), and two long antennae. Their swimming motion is a rapid, jerking dart-and-stop pattern that is highly stimulating to fish feeding instincts. Nutritionally, Cyclops are significantly richer in omega-3 fatty acids (particularly EPA and DHA) and astaxanthin carotenoids than Moina or Daphnia — making them the premium live food choice for colour conditioning and breeding preparation.

Question 2

What size fish can eat Cyclops?

Accepted Answer

Cyclops range from 0.5 mm (nauplii and young juveniles) to approximately 2.0 mm (large adults). This size range makes them suitable for: juvenile fish from approximately 10–15 mm body length onwards (after the microworm and infusoria stage); all nano fish species (Chili Rasboras, Ember Tetras, Microdevario, small Danios) for which Cyclops are an ideal adult food; small to medium community fish (Neon Tetras, guppies, bettas, Rasboras) as a supplement food; and conditioning adults of larger species (Discus, Angelfish, cichlids) where the nutritional benefit rather than size is the key. Very small fry (under 10 mm) cannot eat adult Cyclops but can eat newly hatched Cyclops nauplii.

Question 3

How long before I can harvest Cyclops from the starter culture?

Accepted Answer

The MW Live Cyclops Starter Culture contains an established, actively reproducing population — not eggs or dormant stages. Cyclops are visible immediately on arrival. Initial small harvests can begin within 7–14 days as the population grows in your culture container. Full productive harvest — where 10–20% of the culture volume can be taken daily — typically develops within 3–4 weeks of setting up the culture container. Cyclops reproduce relatively quickly at 22–28°C, with the full nauplius-to-adult cycle completing in approximately 7–12 days under good conditions.

Question 4

How do I feed the Cyclops culture?

Accepted Answer

Cyclops are omnivorous filter feeders — they eat suspended algae, bacteria, yeast and fine organic particles. The simplest feeding approach is dried baker's yeast dissolved in water: a very small pinch (tip of a toothpick) dissolved in a cup of water, added every 1–2 days per 5L of culture. The water should remain clear to very slightly cloudy — cloudy white water indicates overfeeding, which leads to bacterial bloom and culture crash. Spirulina powder at the same tiny dose is an alternative. The easiest long-term feeding method is green water culture: keep a separate 10L container in indirect sunlight, allow algae to grow naturally, and add one cup of this green water to the Cyclops culture every 2–3 days.

Question 5

Do I need aeration for my Cyclops culture?

Accepted Answer

Gentle aeration is recommended but not strictly required. Cyclops tolerate still water better than many other live food organisms, but an air stone at the lowest setting significantly improves culture health by: maintaining dissolved oxygen (Cyclops are sensitive to low oxygen at high densities), keeping suspended food particles evenly distributed, and gently circulating the culture water to prevent dead zones. If you do not have an air pump, keep the culture container partially covered rather than fully sealed, and ensure some surface agitation from water movements. The culture will work without aeration but will support lower maximum population densities.

Question 6

What container size is best for Cyclops culture?

Accepted Answer

A 5–10 litre container is ideal for a productive Cyclops culture. Smaller containers (1–2L) can house Cyclops but have unstable water chemistry and lower production. Larger containers (20L+) produce more Cyclops but require proportionally more feeding and maintenance effort. For a single fish tank owner, one 5–10L culture container typically provides sufficient daily harvest for 1–3 small tanks of nano or community fish. For a fish room with multiple tanks, start with the single culture and split to 3–4 containers within 4–6 weeks using the natural population growth. Use food-grade buckets, clear plastic tubs or small spare aquariums — any clean, non-toxic container works.

Question 7

How do I harvest Cyclops without losing them all?

Accepted Answer

Use a fine-mesh brine shrimp net (100–150 micron mesh is ideal — available at most aquarium shops) or similar fine sieve. Pour 10–20% of the culture volume through the net to collect the Cyclops. Rinse the collected Cyclops briefly with clean dechlorinated water to remove any culture water before adding to the fish tank — this prevents waste and culture water from entering your display tank. Then top the culture container back up to its original volume with fresh aged water. Do not harvest more than 20% at a time — this allows rapid population recovery and prevents culture depletion.

Question 8

Can Cyclops harm my fish or shrimp?

Accepted Answer

No — Cyclops are harmless to fish and adult shrimp. However, there is one important consideration for shrimp breeding: adult Cyclops can prey on very newly hatched shrimp nauplii (under 1–2 mm) in high-density cultures. In a well-maintained shrimp tank with moderate Cyclops density this is not typically an issue — the shrimp babies find refuge in moss and substrate. However, if you are specifically breeding shrimp and trying to maximise juvenile survival, harvest your Cyclops from the culture container and add them to fish tanks as food rather than maintaining them directly in a shrimp breeding tank.

Question 9

Why are some of my Cyclops red or orange?

Accepted Answer

The red or orange coloration in Cyclops is caused by accumulated astaxanthin — the same carotenoid pigment that makes salmon flesh pink and shrimp shells red. Cyclops fed on astaxanthin-rich algae (particularly green water cultures with carotenoid-producing microalgae) accumulate this pigment in their fat bodies. These brightly coloured Cyclops are the most nutritionally valuable for fish feeding — their high astaxanthin content is transferred directly to the fish that eat them, producing measurable colour enhancement in red, orange and pink-pigmented ornamental fish within 2–4 weeks of regular feeding. Reddish Cyclops are a sign of a well-fed, healthy culture.

Question 10

How does Cyclops compare to frozen Cyclops sold in aquarium shops?

Accepted Answer

Live Cyclops provide significantly greater nutritional value than frozen Cyclops for three key reasons. First, the omega-3 fatty acids (EPA and DHA) in live Cyclops are in an intact, biologically active form — freezing degrades some of this fatty acid fraction, particularly the more unstable DHA. Second, the movement of live Cyclops produces a feeding trigger in fish that frozen food cannot replicate — fish that respond moderately to frozen Cyclops often react with dramatically more enthusiasm to live ones. Third, live Cyclops contain living digestive enzymes and natural gut flora that contribute to digestive health in fish. The starter culture from Microworms.in gives you a continuous supply of fresh live Cyclops at a fraction of the cost of purchasing frozen Cyclops regularly.

Question 11

Can I use Cyclops as fry food?

Accepted Answer

Cyclops adults (1.5–2.0 mm) are suitable as fry food for fish that have reached 10–15 mm body length — typically 3–5 weeks after hatching for most small ornamental species. Before this size, newly hatched Cyclops nauplii (0.2–0.4 mm) are appropriate — these hatch naturally within the culture and are extremely nutritious first food. The standard fry feeding progression is: Days 1–7 infusoria and paramecia; Days 7–21 live Microworms (Microworms.in); Weeks 3–8 Cyclops nauplii; Weeks 4+ adult Cyclops and baby Brine Shrimp. Adding Cyclops culture to a fry tank introduces both adult Cyclops and nauplii simultaneously, covering multiple size ranges.

Question 12

How long can I maintain a Cyclops culture?

Accepted Answer

An MW Live Cyclops Starter Culture, properly maintained, is self-sustaining indefinitely. Experienced hobbyists have maintained continuous Cyclops cultures for years from a single starter. The keys to long-term culture health are: consistent but minimal feeding (less is more — overfeeding is the most common cause of culture crash), regular partial water changes (20–30% weekly), gentle aeration, and maintaining a backup culture container so a crash in one container does not end your production. Cyclops cultures are more resilient than Artemia nauplii production (which requires fresh egg hatching daily) and easier to maintain long-term than many other live food organisms.
