Gyrinomimus grahami
Gyrinomimus grahami is a deep-sea flabby whalefish from the Southern Ocean-ish parts of the world - big head, huge mouth, tiny eyes, and a super soft-bodied look. Its adult females are described as dark with reddish tones and orangey fins, and it lives crazy-deep in the bathypelagic zone, so its whole vibe is built around life in perpetual darkness.
Fowleria amblyuroptera
Fowleria amblyuroptera is a very small Indo-Pacific/Western Pacific cardinalfish (to about 4 cm SL) associated with coastal reefs/bays and is primarily nocturnal. Like many cardinalfishes, the male mouthbroods the eggs; in captivity it should be provided with ample shelter and offered appropriately sized meaty foods/planktonic items.
Bathyuroconger fowleri
Bathyuroconger fowleri is a deepwater conger eel, the kind of fish that spends its life down on the slope rather than cruising a reef. Think secretive, bottom-oriented, and very much not an aquarium species - it is more of a cool ID-only eel than something you would ever plan a home setup around.
Siganus vulpinus
Siganus vulpinus is that bright yellow "fox-masked" rabbitfish you see cruising around picking at algae all day. It's generally chill with other fish, but it can get a little bossy with similar-shaped grazers-and those dorsal spines are venomous, so nets and hands need to be treated with respect.
Icelinus oculatus
Frogmouth sculpin is a little coldwater, bottom-hugging marine sculpin from the Pacific coast. It spends its time sitting on the substrate and blending in like a living rock, then darts short distances when food shows up. Super cool fish, but it is absolutely not a warm reef tank animal - it really wants chilly, oxygen-rich water and a calm setup.
Vanderhorstia fulvopelvis
This is a tiny little shrimpgoby from Okinawa (Japan) that lives down on sand and rubble and does the classic prawn-goby thing - hanging at a burrow entrance and relying on a snapping/pistol shrimp roommate for the digging. Its name literally points at a shiny yellow mark on the male's pelvic fin, and the fish itself is patterned with yellow spotting and a clean stripey/barred look.
Quassiremus evionthas
Quassiremus evionthas (Galapagos snake eel) is a marine snake eel (family Ophichthidae) from the eastern Pacific that inhabits areas with sand/gravel/rubble around reefs and is often associated with sandy substrates.
Hoplichthys langsdorfii
Hoplichthys langsdorfii is a little bottom-dwelling ghost flathead from the northwest Pacific (southern Japan down toward the East China Sea). It is a demersal marine predator that hangs on or in the substrate, doing that classic flathead thing of lying still and waiting for food to wander close.
Leptostomias gladiator
This is a deep-sea barbeled dragonfish - long, jet-dark, and built like a little ambush predator with a huge toothy mouth. It lives way down in the bathypelagic zone and uses a chin barbel as a lure, so its whole vibe is "lights-out hunter" rather than anything you'd ever keep in an aquarium.
Uropterygius golanii
This is a small-ish Red Sea snake moray that spends most of its time wedged into rockwork with just a face peeking out. Its plain brown/gray look is super good camouflage, and like a lot of Uropterygius it is more of a secretive ambush predator than an out-in-the-open swimmer.
Amblyeleotris wheeleri
Amblyeleotris wheeleri is that classic shrimp-goby that picks a sandy spot, makes a burrow, and basically turns your tank into a little nature documentary if you pair it with a pistol shrimp. It hangs at the burrow entrance, does the whole lookout routine, and flashes those red bands and blue speckling when it is settled in.
Sebastes glaucus
Sebastes glaucus is a cold-water gray-to-dark rockfish from the northwest Pacific that hangs out deep and close to the bottom. Like other rockfishes it is livebearing (viviparous), and it is the kind of fish you mainly see in public aquariums or fisheries talk - not really a home-aquarium species unless you can provide a large, chilled marine setup.
