Achilles Tang (Acanthurus achilles).

The Achilles Tang is a must have fish known from clear seaward reefs and surge zones where it is usually observed in groups, feeding on filamentous and fleshy algae. However, this attractive, sought-after fish is one of the more demanding members of the Acanthurus genus and is suitable for advanced aquarists only. The aquarium must be spacious, mature, have a vigorous water flow, and contain plenty of live rock which the Achilles Tang will enjoy grazing  Algae from. Include plenty of hiding places that are big enough for your fish to retreat into quickly should it feel threatened, at the same time aiming for an aquascape like aquaroche which allows plenty of open swimming space along the length of your saltwater reef aquarium for such a powerful swimmer. Achilles Tangs are not usually overly aggressive towards tank mates (although rogue specimens have been known), however they will show much hostility towards their own kind and towards other tangs - particularly other members of the Acanthurus genus - so for this reason it is best to house just one specimen per tank and not with any other tangs. It is recommended that the Achilles Tang is the last addition to a set up, as it can be a little territorial to newcomers, especially similar fish species. It is best to source a medium sized specimen as they are more likely to acclimatise well to life in captivity. Conversely, extra large specimens may have a difficult time settling in, so aim for a healthy-looking fish that is neither too small nor excessively large. Avoid any specimens that appear ‘pinched’ in the belly area, and do ask your retailer to show you that your chosen fish is feeding well prior to purchase. Achilles Tangs have a high metabolism and require small frequent feeds throughout the day. Powerful filtration/circulation and a high level of oxygenation are therefore essential for this energetic, voracious eater. Be sure to keep on top of water quality as this fish will not tolerate deteriorating water conditions. A large refugium with living rock can be most useful: macro algae can be cultured on this rock and these pieces rotated with pieces from the main tank, so that the Achilles Tang has a continual supply of natural foodstuffs to graze upon. Take care when handling this species, as the caudal spines are large and can inflict a very painful wound. A period of quarantine can be a valuable procedure for the acclimatisation of all livestock, and it is of particular importance for the Achilles Tang which can be fairly susceptible to developing marine white spot. This can be difficult to treat in the reef aquarium. Ideally the fish should be quarantined and carefully observed in a separate aquarium for at least a fortnight before being introduced into your main display tank. May also be seen on sale as the Red Tail Tang. Juvenile fish display an orange caudal peduncle spine; the large orange teardrop marking in this area appearing as the fish mature. In the wild, the Achilles Tang has been known to hybridise with the Gold Rim Tang (A. nigricans). Prior to purchase, please bear in mind that the Achilles Tang is a very demanding species that requires an aquarium planned around its well-being; the tang should be made the centrepiece of the tank, with all the other variables worked around to suit its specific needs.

Once you have notified us you then have 24 hours to provide us with the following photographic evidence:
For marine fish we require:
  • A clear photograph of the fish in its original sealed bag, you must capture the entire bag with contents and seal still in tact clearly evident before taking the 2nd picture.
  • A clear photograph of the fish out of its sealed bag and water, with its entire rear caudal tail fin cut off.
  • You will know if your fish is dead as it will sink down to the bottom, observe for fin movement and discolouration, most fish sink when they die, but float to the top as they begin to rot. Closely observe the aquatic life upon acclimatising if it hasn’t moved don’t presume its dead but sometimes they are just resting. We advise to add air stone to acclimatising this will increase oxygen level to your live stock. Monitor the fins and gills for any sort of tiny movements, if in doubt call us.
For marine inverts we require:
  • A clear photograph of the fish in its original sealed bag, you must capture the entire bag with contents and seal still in tact clearly evident before taking the 2nd picture.
  • A clear photograph of the marine invert out of its sealed bag and water, with the invert being either cut in half or a sharp object such as a small knife skewered directly through it.
For corals we require:
  • A clear photograph of the fish in its original sealed bag, you must capture the entire bag with contents and seal still in tact clearly evident before taking the 2nd picture.
  • A close up photograph of the coral out of its sealed bag but still in water, (Photographs taken of corals not in water, will not be accepted, as some corals can look distorted/dead out of water).
  • All photographs need to be clear and not distorted. Photographs that do not clearly show their subject will be unable to be accepted as evidence.
  • Failure to be present to sign for your parcel on the first delivery attempt will void all claims. Failure to follow Marine World Aquatics specified DOA reporting procedure will also void any claims.
  • On satisfactory evidence that the marine life is DOA a credit note will be issued.
Please see review our recommended acclimatisation procedures for corals below to ensure your new coral adjusts to your system with the least possible stress.
Acclimatising your new corals is a vital process to ensure they survive and thrive in your system. People use many different methods but most of them are very similar, below is our preferred choice:
  • Unpack coral carefully from box and keep it in the polythene bag or container that it was shipped in.
  • Float the bag or container in your sump area or main tank for around 20 minutes, this will equalise the temperature of the water in the bag to that of the system it is going to be placed.
  • Open the bag or place coral with shipping water into another small container.
  • Using a piece of airline or similar with an air control valve attached, if one not available then just tie a knot in the airline, start a siphon from the main system and drip water slowly from there into the bag/container housing the new coral ( I use around one drip per two seconds ). Once the bag/container is near full then disregard some of the water and continue the process (never put any of the shipping water into your system). I persevere with this process for around 90 minutes to ensure the new coral is fully acclimatised to the new water conditions.
  • Now it is time to remove the coral from bag/container and carefully place it in your tank somewhere near the bottom. Leave it there and raise it slowly over a period of days so as it can adjust to the different lighting on your tank.
This careful process is vital to ensuring your coral or any other livestock’s long term success.
The same above process can be use for Fish and Inverts however this is not recommended, we strongly advise you put all livestock into a quarantine tank for 30 days where you can observe it before placing it into your display tank, make sure you follow the above procedure before placing livestock into your quarantine tank
