Mozambique silverbiddy
Gerres mozambiquensis
Small gerreid (silverbiddy/mojarra) described from Larde Estuary, Mozambique (holotype and paratype). Natural history details beyond the type locality are limited in readily available references; like other Gerreidae, it likely forages on benthic invertebrates in shallow estuarine/coastal habitats.

Orange chromide
Pseudetroplus maculatus (syn. Etroplus maculatus)
This is that cute little Indian/Sri Lankan cichlid with the big black "shoulder" spot and a warm gold/orange glow when it's happy. It'll do the classic cichlid thing where it gets a bit pushy when breeding, but most of the time it's pretty chill-especially if you keep a small group. Super cool bonus: the parents actively tend the eggs and fry, and the babies even graze on the parents' skin mucus for a bit.
Pacific Four-Eyed Fish
Anableps dowii
This is the goofy, super-cool "four-eyed" fish that cruises the surface and looks like it's wearing little goggles-each eye is split so it can see above and below the water at the same time. They're active, always on the move, and they really shine in a long brackish tank where they can patrol the top like little patrol boats.
River garfish
Zenarchopterus xiphophorus
This is a slim, surface-hugging halfbeak from the mouth of a river in Sumatra, and it has that classic "half-beak" look where the lower jaw sticks out. Its biology is way more "wild fish" than "pet shop fish" - think open-water cruising up top and spooking easily if the tank is busy or uncovered.
Sand catfish
Arius arenarius
Arius arenarius is a small-ish sea catfish from coastal waters around southern China and Taiwan. It is a bottom-hugging brackish-to-marine catfish with the classic ariid look - chunky head shield, whiskers, and nasty fin spines that can absolutely ruin your day if you grab it wrong. This is more of a brackish/marine oddball than a community freshwater catfish, so it really fits best in a proper brackish setup.
Senegal needlefish
Strongylura senegalensis
This is a long, sleek coastal needlefish with that classic beak full of teeth, built to rocket around the surface and ambush smaller fish. It naturally cruises marine water but also pushes into estuaries and brackish lagoons, so it is a true salt-to-brackish kind of fish. Cool predator, but it gets way too big for normal home aquariums and really needs serious space and a tight lid.
Silver moony (Mono)
Monodactylus argenteus
Silver moonies are those shiny, diamond-shaped "mono" fish you see cruising nonstop in brackish tanks-super active and way more fun to watch when they're in a proper group. They start out in estuaries (often sold too small and too fresh), and the big "gotcha" is they really want you to ramp them up to stronger brackish/near-marine as they grow. Feed them like a hungry, messy omnivore and give them swimming room, and they're absolute show-stealers.
Silver Tiger Perch
Datnioides polota
Datnioides polota is that big, bold tiger-striped fish that just owns the whole tank-thick-bodied, shiny silver, and those dark bands look like someone painted them on. The fun part is watching it stalk around like a little underwater predator, especially at feeding time, but it's also one of those fish that'll make you plan the whole setup around it.
Singapore glassy perchlet
Ambassis kopsii
Ambassis kopsii is one of those cool little see-through mangrove/estuary fish that likes to hang out in a tight group, flashing silver in the light. It naturally lives where fresh and saltwater mix, so it does best when you treat it like a calm, slightly brackish schooling fish and give it lots of friends.
Slender mudskipper
Zappa confluentus
This is a tiny New Guinea mudskipper that lives around tidal mudflats by murky, brackish river water, and it can do the classic mudskipper trick of air-breathing when it is out of the water. In aquarium terms, think of it less like a regular "fish" and more like a little amphibious goby that wants a land area, lots of damp mud/sand to perch on, and calm brackish conditions.
Speckled goby
Redigobius isognathus
A tiny estuary goby with a neat checkered body pattern and a surprisingly big mouth for such a small fish. It hangs out on the bottom, scooting between shells and rocks, and will happily pick at tiny crustaceans and other bite-size foods. Folks sometimes confuse it with the similar R. bikolanus, and it does great in lightly brackish setups with hard, alkaline water.
Spotted archerfish
Toxotes chatareus
This is the classic archerfish that'll actually "shoot" insects with a jet of water-ridiculously fun to watch once it settles in. It's a surface-hunter from mangroves and estuaries, so it likes harder, alkaline water and lots of open top-level swimming room (with a tight lid, because they jump). Give it a big, long tank and a group of similar-sized buddies, and it turns into a real centerpiece fish.
