Marine Fish Perfect Health Promise
All marine fish have a Perfect Health Arrival guarantee. For the following reasons, we cannot guarantee beyond that.
A number of different reasons can affect why a marine fish does not settle into its new environment. These range from:
- Unsuitable water conditions: incorrect pH, high ammonia and nitrite levels.
- Tank bullies: some marine fish are very passive and will not mix well with more boisterous tank mates.
- Incorrect tank size: please research the fish you are buying, as some will become stressed in a tank that is too small.
If you have any problems on arrival
Please contact us straight away and we will extend your guarantee until the fish is healthy again. You must call on the arrival day to activate this.

About this fish
What is its maximum size?
Lamarck's Angelfish (Genicanthus lamarck) can grow to approximately 25 cm (10 inches) in length, although aquarium specimens are often somewhat smaller.
It is a peaceful, active open-water swimming angelfish belonging to the Genicanthus genus, commonly known as Swallowtail Angelfish.
One of its most interesting characteristics is its sexual dimorphism, meaning males and females have noticeably different colour patterns.
Males: Silvery-white bodies with black horizontal stripes, distinctive black pelvic fins and elongated tail streamers.
Females: Generally have a more pronounced black stripe along the upper body, with different tail and fin markings.
Where is its origin and where is it exported from?
Lamarck's Angelfish originates from the tropical Indo-West Pacific region.
Its natural distribution extends across:
Indonesia.
Philippines.
Malaysia.
Papua New Guinea.
Vanuatu.
Southern Japan.
Northern Australia.
Great Barrier Reef region.
It inhabits shallow reef crests, outer reef slopes and deeper reef environments, generally at depths of approximately 10–50 metres.
Unlike many other angelfish, it spends much of its time swimming above the reef in open water, feeding on plankton.
It is frequently exported for the marine aquarium trade, particularly from Indonesia and the Philippines.
Is it reef compatible?
Reef safeLamarck's Angelfish is considered one of the most reef-compatible marine angelfish.
Unlike many large and dwarf angelfish, it does not normally graze on corals or pick at ornamental invertebrates.
Its natural diet consists primarily of zooplankton and other small drifting organisms in the water column.
Potential compatibility includes:
LPS corals: Generally safe.
SPS corals: Generally safe.
Soft corals: Generally safe.
Zoanthids: Generally safe.
Clams: Generally safe.
Shrimps and ornamental invertebrates: Generally safe.
Its plankton-feeding behaviour makes it an excellent choice for established reef aquariums.
What should I feed it?
Lamarck's Angelfish is a planktivore and requires a varied diet rich in marine proteins.
Recommended foods include:
Frozen mysis shrimp.
Enriched brine shrimp.
Calanus.
Copepods.
Marine zooplankton preparations.
Finely chopped shrimp and other marine seafood.
High-quality marine pellets.
Quality marine flakes.
Unlike many other angelfish, it does not have the same dietary dependence on sponge-based foods.
Several small feedings throughout the day are beneficial because of its natural feeding behaviour in open water.
How many can I keep?
Lamarck's Angelfish is one of the better angelfish species for keeping in groups.
It naturally forms social groups and harems, often consisting of one dominant male and several females.
Recommended stocking arrangements include:
A single specimen.
A compatible male and female pair.
One male with several females in a sufficiently large aquarium.
It is important to avoid keeping multiple mature males together, as they may become territorial and fight.
Interestingly, this species is a protogynous hermaphrodite, meaning females can change sex and develop into males when social conditions require it.
How compatible is it with other fish?
Lamarck's Angelfish is generally peaceful and one of the more community-friendly marine angelfish.
It usually coexists well with a wide range of marine fish, including:
Tangs.
Clownfish.
Anthias.
Wrasses.
Gobies.
Blennies.
Other peaceful angelfish.
Reef-safe community fish.
It is generally less territorial than many large angelfish and can make an excellent addition to a peaceful reef community.
Avoid housing it with overly aggressive fish that may intimidate it or prevent it from feeding properly.
