Paraheminodus longirostralis
This is a deepwater armored searobin - basically a little walking tank of a fish with bony plates and feeler-like rays it uses to hunt along the bottom. Its claim to fame is the extra-long snout projections, and it lives way down on the slope, not in the usual home-aquarium zone. Realistically, this is a research-trawl kind of species rather than something you keep at home.
Umbrina analis
Umbrina analis is an Eastern Pacific sciaenid (drum/croaker) that inhabits inshore soft bottoms (sand/mud) from the tip of Baja and the SW Gulf of California to Colombia, typically near the bottom in surf zones, bays, and shallow coastal waters (about 1–50 m). It is a carnivore feeding mainly on mobile benthic invertebrates (crustaceans, worms, and mollusks).
Nansenia longicauda
This one is a deepwater pencilsmelt that lives way down in the mesopelagic zone, so its more of a research-species than an aquarium fish. It tops out around 13 cm and seems to show up in patchy spots in the subtropical Atlantic and North Pacific, typically hundreds of meters down.
Gymnothorax porphyreus
Gymnothorax porphyreus is a chunky, cold-to-cool water moray from the South Pacific that hangs out on rocky reefs and wedges itself into caves with just the head out. It tops out around a meter long, so it is absolutely a big, powerful predator even though it is not one of the giant 2-meter morays. If you ever see one offered for home aquariums, the big gotcha is temperature - this is not a tropical reef eel.
Zebrias lucapensis
A small marine demersal sole (family Soleidae) described from Lucap Bay / Hundred Islands area of Lingayen Gulf, Philippines; known from very limited records. Aquarium care information is not species-specific in the literature; if kept, husbandry would likely follow general small marine sole/flatfish needs (fine sand, peaceful tankmates, benthic meaty foods).
Vinciguerria mabahiss
Vinciguerria mabahiss is a tiny deepwater lightfish from the Red Sea that uses rows of photophores (light organs) for counter-illumination - basically a living stealth mode in the midwater dark. Its whole lifestyle is mesopelagic (open-water, deep), so its "care" is really more science-lab territory than home aquarium stuff.
Elops affinis
Elops affinis is a sleek, super-silver coastal predator (a ladyfish) that cruises surf zones, bays, and estuaries in schools and will happily push into brackish lagoons. Its life cycle is pretty cool - spawning happens offshore, and the clear, ribbon-like larvae drift in toward the coast before they grow into those fast, fork-tailed little missiles.
Wheelerigobius maltzani
This is a tiny West African coastal goby that lives right down on the bottom in warm, shallow inshore water. Its big appeal is the "little predator" vibe - it perches, scoots, and hugs structure like a classic goby, but its real-world habitat is marine shoreline rather than a typical freshwater community setup.
Synchiropus splendidus
This is the classic mandarin dragonet-the little reef crawler that looks like someone hand-painted neon blue and orange squiggles onto a fish. It spends basically all day pecking at live rock for tiny pods, and at dusk you can sometimes catch the pair-spawning "rise" if you keep a bonded male/female. Absolutely reef-safe, but it's one of those fish that does amazing only when the tank is truly mature and full of microfauna.
Urogymnus granulatus
This is a large, heavy-bodied whipray with a dark disc sprinkled with small pale spots and a distinctive white tail beyond the sting. It uses shallow inshore habitats including mangroves and estuaries (juveniles often in brackish areas). Juveniles have been documented actively producing clicking sounds during aggregations/defensive interactions.
Coryphaenoides marshalli
This is a deep-sea grenadier (rattail) from the Gulf of Guinea - think big head, huge eyes for the dark, and that classic long tapering tail. It lives way down on the slope, so it's not an aquarium fish in any realistic sense, but it's a really neat example of how fish are built for cold, high-pressure life.
Hexagrammos octogrammus
Masked greenling is a cold-water North Pacific greenling that hangs around shallow rocky areas and kelp, cruising the bottom and picking off crustaceans. One of the coolest quirks is the family trick of eye/cornea color shifting in different light, which is just wild to see in person. This is not a typical home-aquarium fish - it gets fairly big and wants chilly, super-oxygenated marine water.
