Achilles Tang

Social Sharing

The Achilles Tang is an amazing looking tang that gets to about 9 inches as adults but they have a very bad track record in aquariums over the years. They have a similar reputation as the Powder Blue Tang for their short life spans due to not adjusting to aquarium life and the onset of cryptocaryon (marine ich). They can be very difficult to get on foods, especially the common foods like pellets, flakes and thawed fish foods. Many authors recommend giving them nori (algae sheets) a few times a week. For a new introduced Achilles Tang I would offer it to them all day every day to make sure they have they are eating.
The Achilles Tang is often found near seaward reefs where the water flow is highly turbulent. High and turbulent water flow with high levels of dissolved oxygen in the aquarium are recommended. They may not get on well with conspecifics or even other tangs. Keep them in a 120 gallon aquarium or larger and feed often.
An expensive fish that might be quite demanding and difficult to keep. Leave this one be until you get lots of experience in keeping tangs or leave it on the reef.

Life span : 7 years or longer

Size : 9 inches (24 cm)

Water Parameters : pH 8 - 8.4 | Temperature 78°F - 82°F (26°C - 28°C) | Specific Gravity 1.022 - 1.026

Origin / Habitat : Western Pacific, Hawaiian and Pitcairn islands - found near seaward reefs often alone or in small groups

Temperament / Behavior : If you have a big enough tank you can keep multiple tangs but do not keep conspecifics in the same tank to avoid aggression.

Breeding / Mating / Reproduction : Extremely difficult, open water egg scatterers

Tank Size : 120 gallon minimum - active swimmers

Compatible Tank Mates : One to a tank, may tolerate other tang species like the Zebrasomas in larger setups.

Reef Tank Compatible? : Yes

Disease : Freshwater, pH adjusted dips of a minute or two may help. These tangs are known as "ich magnets". Keep a cleaner shrimp like the Skunk Cleaner Shrimp in with them.

Diet / Fish Food : Primarily an herbivore that needs to be fed algae (nori sheets) on a regular basis. You need live rock too for better results because they will pick at it in between meals.
