  3. Popular Clownfish • Ocellaris Clownfish (AmphiprionOcellaris). • Everyone who has a clownfish either has one or has had one in the past. It’s cheap, plentiful and great for beginners. • Percula Clownfish(AmphiprionPercula). • Just as popular as the Ocellaris Clownfish, but more expensive, not as common but just as hardy.

  4. Economic Importance • The research estimates that by 2011, Taiwan could breed 2 million clownfish and generate $100 million in the lucrative ornamental fish market, while helping save the species in the wild. • 200,000 clownfish can generate $10 million in revenues annually. • Tomato clownfish have a positive economic importance for humans through the pet trade industry.

  5. Finding Nemo • Singapore • Shanghai • Italy • China • Taiwan TaiKong Co • Tennessee-Sustainable Aquatics

  6. Market Prices • Anywhere from $15-$120.

  7. Life Cycle • Hatching usually takes from 6 to 15 days. • The clownfish have a larval period of between 10 and 20 days. • From day three to eight the larvae will grow very fast. • Day eight to eleven are dangerous days. This is the timeframe when the larvae start to look like adults and metamorphosize. • During this time the larvae are more tolerant to water conditions however they can be very sensitive to fright. • Its best not to move the small clownfish until they have reached atleast 14 days or until all have metamorphosized. • From time of hatch to attaining a size of 2.5 to 3cm can take 12 weeks.

  9. Breeding • The ideal setup for clownfish larvae is to have a central standpipe in the round tank and have around the standpipe a mesh screen of between 100 and 300 microns. • The different mesh sizes are used for different sized live feeds such as rotifers and artemia. • Water overflows into a sump where there is biological filtration and mechanical filtration. • A low volume pump then pumps water back to the tank at a very slow rate, just enough to cause the water to slowly circulate and keep the larvae moving. • An airstone may be required in the centre of the tank along the side of the screen to ensure that it does not block up.

  10. Feeding • For the first two days live food densities should be kept high. • Live bait and micro-organisms, such as rotifers and copepods, are needed to suit the needs of the larvae. • Pellet diet is only fed to the fry after they grow to 20-day-olds. • Sustainable Aquatics created their own food that is high in protein, vitamins and vegetation material to ensure high growth.

  11. Water Chemistry • The water quality should be kept high and the water well circulated. • The temperature should be around 24°C - 27°C. • The salinity at 27-30 ppt. • The pH from 8.0 to 8.4. • An ideal larval rearing tank is a round plastic or fibreglass tank with a water holding capacity of between 50 and 150 liters. • The tanks can be setup as having a filter and reticulating water or stand alone and just using airstones and partial water changes.

  12. Advantages and Disadvantages • Advantages • Low mortality. • Accustomed to people. • Easy to acclimate. • Bright and beautiful coloration. • Disadvantages • Aggressive and territorial. • Some species can be expensive.
