About the Ocellaris clownfish

Ocellaris clowns are that classic orange clownfish look-three white bars, a little black edging, and a ton of attitude packed into a small fish. They'll "pick a spot" in the tank (often a corner or a coral) and do that cute hover-wiggle thing, and a bonded pair will usually settle in fast and act like they own the place.

Aleutian skate

Bathyraja aleutica

This is a big, cold-water deep-slope skate from the North Pacific that cruises muddy bottoms and eats chunky benthic prey like crabs and shrimp. The really cool bit is its egg-laying skate life - it does distinct pairing (the classic skate "embrace") and drops those tough egg cases on the seafloor. Not an aquarium fish at all unless you're basically running a public-aquarium-style chilled system.

Antarctic dragonfish

Vomeridens infuscipinnis

Deep down around Antarctica, this sleek dragonfish cruises the water column like a little submarine, nearly neutrally buoyant so it can hover above the seafloor. It munches almost exclusively on Antarctic krill and lives in near-freezing water 500-800 m down, so it is a cool species to read about, not one for home tanks.

Arabian demoiselle

Neopomacentrus sindensis

A small lyretail damsel from the Persian Gulf and Arabian Sea, it hangs in loose groups around coral heads, rocks, and even pier pilings picking zooplankton from the flow. Think classic damsel toughness with a slightly milder attitude than the real bruisers, plus subtle yellow tail accents. Males clean a patch, get a mate to lay eggs there, and then stand guard fanning the clutch.

Arctic rockling

Gaidropsarus argentatus

This is a deepwater North Atlantic rockling (a cod relative) that hangs out on soft bottoms way down the slope. It is a cold-water, bottom-hugging predator that snoots around for crustaceans and will also take small fish when it gets the chance.

Atlantic pomfret

Brama brama

Brama brama is the Atlantic pomfret (aka Ray's bream) - a deep-bodied, open-ocean pelagic fish that cruises around in small schools and follows water temps. It is a legit big, wild marine species (not an aquarium fish) that eats other small sea critters like fish and squid, and it ranges across a huge chunk of the Atlantic plus parts of the Indian and South Pacific.

Affinis blind cusk-eel

Barathronus affinis

Barathronus affinis is a tiny, super-weird deep-sea blind cusk-eel from the western-central Indian Ocean. It is one of those gelatinous, loose-skinned brotula-type fishes that live way down in the dark and are basically never seen alive, so almost everything we know comes from preserved specimens and taxonomic work.

African red snapper

Lutjanus agennes

This is a true snapper from West Africa - a big, fast-growing predator that goes from coastal reefs to brackish lagoons and estuaries (especially as a juvenile). Super cool fish in the wild, but it gets absolutely huge and will eat smaller tankmates once it has the mouth for it, so its really more of a public-aquarium scale animal than a home-aquarium fish.

Allis shad

Alosa alosa

Gorgeous silver, fast-swimming shad that spends most of its life in the sea and then surges up big rivers in noisy, surface-spawning schools. It grows huge for a herring-type fish and needs cool, ultra-oxygenated water and tons of open space, so it is a public-aquarium species rather than a home tank fish.

Annandale's zebra sole

Zebrias annandalei

Zebrias annandalei is a small demersal sole from coastal India that inhabits sandy or muddy bottoms and buries for camouflage. It is rarely kept in home aquaria and would require a specialized marine sand-bottom setup and appropriate feeding.

Australian sawtail catshark

Figaro boardmani

Figaro boardmani is a small, deepwater Australian catshark with these cool saw-like ridges of spiny denticles along the tail and a neat pattern of dark saddle bands. It lives way down on the outer continental shelf and slope, so its natural water is cold, dim, and stable - totally not a typical home-aquarium fish. Diet-wise its a predator that goes after fish, crustaceans, and cephalopods.
