Banggai Cardinalfish
Pterapogon kauderni
Elegant black-and-silver with distinctive elongated fins and bold stripes. A mouthbrooder — the male incubates eggs in his mouth until hatching. One of the few marine fish regularly bred in home aquaria.
Coral Beauty Angelfish
Centropyge bispinosa
Deep blue body with orange-yellow sides and purple highlights. Hardiest of the dwarf angels. Generally reef-safe but may nip soft corals.
Firefish Goby
Nemateleotris magnifica
Elegant dartfish with a fiery orange-red tail and white-to-yellow body. Shy but beautiful. Tends to jump so a tight-fitting lid is essential.
Flame Hawkfish
Neocirrhites armatus
Vivid red with black dorsal markings and outline — perches atop gorgonians and Acropora waiting to ambush prey. Completely reef-safe with corals but will eat small shrimp. Charismatic and bold.
Foxface Rabbitfish
Siganus vulpinus
Bold yellow body with intricate brown-and-white facial patterning. Has venomous spines so handle carefully. Outstanding algae and nuisance weed grazer.
Green Chromis
Chromis viridis
The quintessential schooling reef fish — shimmering apple-green in open water above Acropora. Incredibly hardy and peaceful. Best kept in groups of 6+ for the most natural look.
Kole Tang
Ctenochaetus strigosus
Brown tang covered with fine yellow-orange spots. Excellent detritivore and algae grazer. More peaceful and compact than most tangs. Great reef fish.
Lawnmower Blenny
Salarias fasciatus
The go-to algae control fish for reef tanks — relentlessly grazes film algae and hair algae off rocks and glass. Camouflaged brown-grey with warty skin and charismatic perching behaviour.
Longnose Hawkfish
Oxycirrhites typus
Instantly recognisable by its elongated snout and white body with red grid pattern. Perches in gorgonian sea fans and black coral, propping itself on its fins. Bold and long-lived in captivity.
Lubbock's Fairy Wrasse
Cirrhilabrus lubbocki
Strikingly colourful — males flash vivid red, orange, and yellow with iridescent highlights during display. Peaceful and active; best kept as one male with several females. A jewel of the mid-water column.
Maroon Clownfish
Premnas biaculeatus
The largest clownfish species, maroon-red with bold white stripes. Highly aggressive — best kept as a single specimen or bonded pair. One of the most striking reef fish available.
Melanurus Wrasse
Halichoeres melanurus
Dazzling rainbow colouration — females green-blue, males sporting a vivid magenta-and-green pattern. A sand-diver that buries to sleep. Natural predator of flatworms and pyramid snails.
Midas Blenny
Ecsenius midas
Brilliant golden-yellow with a flowing, eel-like body. Often mimics Lyretail Anthias in colour. Perches on rockwork and darts into crevices when startled — reef-safe and entertaining to watch.
Neon Goby
Elacatinus oceanops
Tiny electric-blue-striped goby renowned as a cleaner fish — will pick parasites from larger tank mates. Ideal for nano reefs. The Caribbean's answer to the cleaner wrasse.
Ocellaris Clownfish
Amphiprion ocellaris
The iconic clownfish made famous by Finding Nemo. Hardy, peaceful, and symbiotic with anemones. Excellent beginner saltwater fish.
Orchid Dottyback
Pseudochromis fridmani
Vivid orchid-purple throughout — one of the most coveted nano reef fish. A Red Sea endemic that is now tank-bred widely. Bold personality for its size; can be aggressive to smaller fish.
Pajama Cardinalfish
Sphaeramia nematoptera
Unmistakable with its yellow head, dark mid-band and polka-dotted orange rear — like a fish in pyjamas. Nocturnal schooler that hovers in groups near branching corals. Very peaceful and reef-safe.
Pink Skunk Clownfish
Amphiprion perideraion
Pale pink-orange with a single white dorsal stripe and cheek bar. One of the smallest and most peaceful clownfish — ideal for nano reef tanks alongside Magnificent Anemones.
Purple Firefish
Nemateleotris decora
One of the most visually striking nano reef fish — white to yellow body fading into vivid purple-magenta. Peaceful and reef-safe; will jump, so a tight lid is essential.
Royal Gramma
Gramma loreto
Arguably the most striking Caribbean reef fish — front half vivid purple, rear half bright yellow. Hardy, peaceful, and reef-safe. Tends to hang upside-down under ledges mimicking its cave habitat.
Scissortail Dartfish
Ptereleotris evides
Slender, schooling dartfish with a distinctive forked tail and blue-grey body. Best kept in pairs or small groups; will share a burrow. Reef-safe and active in the mid-water column.
Scopas Tang
Zebrasoma scopas
Elegant, understated tang ranging from brown to blue-grey with fine markings. Peaceful and hardy. Excellent algae grazer and reef-safe.
Six Line Wrasse
Pseudocheilinus hexataenia
Active and colourful wrasse with six horizontal blue stripes. Pest controller — eats flatworms and small pests. Can be territorial with similar species.
Tailspot Blenny
Ecsenius stigmatura
One of the most popular reef blennies — mottled tan with a characteristic black tail spot and expressive eyes. Grazes on algae and is generally reef-safe with corals. Full of personality.
Tomato Clownfish
Amphiprion frenatus
Bold, tomato-red with a single white cheek stripe. Hardy and beginner-friendly, closely related to the Ocellaris. Pairs readily with bubble-tip anemones in captivity.
True Percula Clownfish
Amphiprion percula
Slightly more vibrant coloring than its ocellaris cousin. Pairs beautifully with Bubbletip or Magnificent anemones. Very popular reef fish.
Yellow Tang
Zebrasoma flavescens
Brilliant solid yellow tang from Hawaiian reefs. A staple of the reef aquarium hobby. Excellent algae grazer and generally peaceful.
Yellow Watchman Goby
Cryptocentrus cinctus
Vibrant yellow with blue spots, best known for its mutualistic relationship with pistol shrimp — the shrimp digs and maintains a shared burrow while the goby stands guard. A staple of any reef tank.
