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.
Small Chinese silver-biddy
Gerres decacanthus
Think of a quick, silvery sand-sifter that cruises shallow bays and estuaries, flashing as it turns. In a tank it uses that stretchy mojarra mouth to puff sand and pick tiny critters, and it really settles in when kept as a small group with open swimming space and a soft sand bed.
Southern longfin goby
Favonigobius lateralis
Neat little sand-dwelling goby that hangs out in seagrass beds and sandy estuaries around Australia and New Zealand. It perches on the bottom and even shimmies into the sand, so a fine sandy substrate is a must. Keep it in lightly brackish water and it will happily pick at small meaty foods.
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.
Spotted green pufferfish
Dichotomyctere nigroviridis
This is the classic green spotted puffer: bright lime-green with bold black spots and a ton of attitude packed into a football-shaped body. They're crazy interactive and will beg like a puppy, but they're also little beaked predators that need crunchy foods to keep their teeth worn down. The big "gotcha" is water: they're not a lifelong freshwater fish-brackish (and often more marine-leaning as they mature) is where they thrive.
Spotted scat
Scatophagus argus
Spotted scats are those chunky, disc-shaped brackish fish with the peppered "polka dot" pattern that changes a lot as they grow. They cruise around in groups, eat basically anything you offer, and they're tough as nails-just don't fall into the super common trap of keeping them in straight freshwater long-term.
Stellate tadpole-goby
Benthophilus stellatus
This is one of those weird little bottom-huggers from the Black Sea/Azov/Caspian region - big head, narrow tail, and a body covered in tiny bony bumps. It spends its time on mud and sand in cooler water, picking at small invertebrates, and it is way more of a coldwater/brackish oddball than a typical tropical aquarium goby.
