Amphiprion ocellaris – Ocellaris Clownfish
• One of the most common grown clownfish.• Hardy, cheap, abundant and a great first
saltwater fish.• Makes a great movie.
Economics of Clownfish
• Most inexpensive is $12.99 for Ocellaris.• Most expensive is $249.99 for Super Black Ice
Snowflake Clownfish.
• Clownfish are among the most popular species of aquarium fish in the world.
• A United Nations report found that at least 145,000 of them were traded internationally between 1997 and 2002.
• Raised in Singapore, Taiwan, and the US.• By 2011, Taiwan could breed 2 million
clownfish and generate NT$100 million in the lucrative ornamental fish market, while helping save the species in the wild
Life cycle of clownfish • The eggs looked like little capsules about 2
to 3 mm long and 1 mm wide.• The eggs take about 8 to 10 days to hatch.• Larval period of 10 to 20 days.• Critical stages are the two first days of
larvae life and the moment metamorphosis takes place, when mortality can be high.
• After about 25 days, juveniles can be moved to a different tank to begin acclimation.
• Clownfish are protandrous hermaphrodites.
Clownfish eggs
Reproduction• Clownfishes were among the first ornamental species to be
commercially bred in the 1980’s.• Clownfishes typically reach sexual maturity at an age of 8-18
months.• Spawning occurs during daylight hours and a small clutch of
eggs is laid usually on the underside of a rock or other solid base.
• A typical nest may contain 100-300 eggs for the smaller species such as percula, or up to several thousand eggs for maroon clownfish.
• At an age of 10-14 days clownfishes will undergo metamorphosis.
• This is when clownfish “earn their stripes” and will begin to look like real clownfish.
Production methods
• RAS tank systems used for Breeding Adults.• Prior to hatching, the eggs are moved to a
small tank with very low water movement.• Round tank is preferred to enhance livability.• Tank should be fitted with both mechanical
and biological filters.
Feeding
• The first few days the fry should be fed live rotifers that have been prepped and fed phytoplankton.
• After fry reach about 5mm start to feed brine shrimp.
• By day 21 start feeding crushed flaked food and large brine shrimp.
Age / Approx. Size Characteristic Food Hatch to day 6-8 / 2.8 to 4.3 mm
Larvae Rotifers
Days 6-14 / 4.3 to 5.2 mm
Metamorphosis/early juvenile (body shape changes from tapered to oval)
Rotifers, powdered flakes
Days 7-14 / 5.2 to 6.8 mm
Forming head stripes Rotifers, brine shrimp nauplii, powdered flakes
Days 14 to 21/ 6.8 to 10 mm
Forming mid-body stripes
Brine shrimp nauplii, powdered flakes
Days 21 to 48 / 10 mm to 3/8 inch
Forming black edges to pectoral fins
Crushed flakes, Cyclop-Eeze
Days 48 to 64 / ½ inch to 5/8 inch
Forming tail stripes and black edges around stripes
Crushed flakes, Cyclop-Eeze, frozen spirulina-enriched adult brine shrimp
Days 64 to 90 / ½ inch to 1 inch
Will continue to form black edging
All the above plus whatever else they can fit into their mouths
Water Chemistry• The temperature should be around 24°C - 27°C.• Salinity should be about 28 ppt.• NH3 should be less than 3 ppm.• pH should be kept about 8.0.• Larval tank should be round.• Use airstone for O2 delivery.• Fry should be kept in very low light prior to 21 days of age.• Slow well circulated water.
Advantages and Disadvantages
• Advantages• Hardy fish• People tolerant• Easy to raise• Very colorful• Numerous species to
choose from.
• Disadvantages• Some can be very
expensive• Most still wild captured.• Can be territorial.• Saltwater species
