Patchwork stingaree
Urolophus flavomosaicus
A gorgeous round ray from northern Australia with a yellow-mosaic pattern that really pops. It is a deep-water sand-sitter that spends a lot of time buried with just the eyes showing, so when it moves you get those fun, floaty glides across the bottom.
Paxton's slickhead
Conocara paxtoni
Conocara paxtoni is a deep-sea slickhead from the Tasman Sea, and its whole vibe is pure "mystery fish" - its known record is from a single specimen taken around 2450 m deep. It's a fairly big, streamlined bathypelagic/benthopelagic fish (for a slickhead), but it is absolutely not an aquarium species (deepwater pressure/temperature requirements make that a no-go).
Pearly-finned cardinalfish
Jaydia poeciloptera
This is a nocturnal Indo-West Pacific cardinalfish that spends the day tucked away (even hiding in holes in soft mud) and comes out at night to feed. The really cool part is the breeding style - they pair up, and the male mouthbroods the eggs like a little floating nursery.
Pearly hairtail
Trichiurus auriga
This is a real-deal marine cutlassfish - long, silver, and built like a ribbon with a mouth full of grabby teeth. Its care is basically "public-aquarium predator" territory: it wants big open swimming room, strong filtration, and meaty foods, and it will happily eat tankmates that look snack-sized.
Peppered catshark
Galeus piperatus
This is a little deepwater catshark from the northern Gulf of California with a cool "peppered" look - fine black dots all over a gray body. It lives way down on the slope (hundreds to over a thousand meters deep), so its real-world conditions are cold, dark, and high pressure, which is why its not an aquarium fish in any normal sense.
Peppered moray
Uropterygius polystictus
Uropterygius polystictus (the peppered moray, aka many-spotted moray) is a reef-associated moray from the Eastern Pacific that spends most of its time wedged into rockwork and popping its head out to watch the room. It tops out around 72 cm/28 in, so its "hiding in the rocks" vibe can fool people into under-tanking it - give it serious caves and a truly escape-proof lid.
Peruvian chromis
Azurina intercrusma
Azurina intercrusma is a bigger, cool-water chromis from the rocky reefs off Peru down into Chile. It spends a lot of time out in the water column grabbing zooplankton, and in the wild the male will guard and fan the eggs after spawning. Not really a typical home-aquarium fish unless you're set up for a temperate marine system (most reef tanks run too warm).
Peterson's grenadier
Ventrifossa petersonii
Deepwater marine bathydemersal grenadier (family Macrouridae) from the Indian Ocean region; reported depth range about 296–1019 m (often ~350–700 m). Not a practical aquarium species due to deepwater capture/handling constraints and cold, dim habitat requirements.
Petrale sole
Eopsetta jordani
A right-eyed flatfish from the Pacific coast, this guy lies buried in sand and snaps up crabs, shrimp, and small fish that wander too close. It gets big and comes from cold, temperate saltwater, so it is really a public-aquarium sort of fish rather than a home tank pick.
Phenax brotula
Brotula phenax
Brotula phenax is a marine cusk-eel (brotula) from Vietnam waters in the western-central Pacific. Its species name basically means "imposter" because it looks super close to the better-known Brotula multibarbata, and honestly thats a good hint that this one is still pretty poorly documented in the hobby.
Philippine cardinalfish
Ostorhinchus mydrus
Ostorhinchus mydrus is a little marine cardinalfish from the Philippines that hangs around coral reefs and comes alive at night. Like a lot of cardinals, its claim to fame is the male carrying the eggs in his mouth - super cool behavior if you ever get to see a pair settle in and spawn.
Philippine croaker
Johnius philippinus
Johnius philippinus is a tiny little croaker from the Philippines (family Sciaenidae) that lives down near the bottom in marine water. Its known records are super limited (FishBase lists it only from the Davao Gulf area), so its real-life habits in the aquarium trade are basically a mystery - this is more of a scientific/market-fish kind of species than a home-aquarium fish.
