Acheilognathus fasciodorsalis
Acheilognathus fasciodorsalis is a freshwater bitterling endemic to Vietnam. Like other bitterlings (Acheilognathidae), reproduction involves females using an ovipositor to deposit eggs in freshwater mussels.
Wallaciia virgatula
This is one of the little "dwarf" pike cichlids (recently moved out of Crenicichla into Wallaciia), so you get that sleek pike-cichlid look and attitude in a genuinely small package. Expect a smart, ambushy micro-predator vibe - it will hang around cover, watch everything, then dart in like a mini torpedo when food hits the water.
Rita rita
Rita rita is a big, predatory river catfish from South Asia that spends most of its time cruising the bottom and waiting to ambush food. Juveniles can look kind of "cute and manageable" in the shop, but this fish is basically a tank-buster that will eventually want serious space and will absolutely snack on anything it can fit in its mouth.
Rineloricaria henselii
Rineloricaria henselii is a small loricariid (whiptail) catfish from southern Brazil (reported from the Cubatão River, Santa Catarina) reaching about 7.5 cm standard length.
Farlowella acus
Farlowella acus is that classic twig-looking whiptail that can sit on wood and basically disappear - it really does look like a little stick with fins. It is super chill and spends most of its time grazing and picking at surfaces, so it does best in a mature tank with stable water and plenty of stuff to cling to.
Tanichthys albonubes
White Clouds are tiny little stream minnows with that neat glowing stripe and red-tipped fins, and they look way better the cooler you keep them. They're super active in a group and do this constant "busy schooling" thing in the top/middle of the tank-really fun fish when you give them space to zip around.
Betta albimarginata
This is one of those wild bettas that feels more like a tiny aquarium predator than a "fancy fin" betta-sleek, quick, and always watching what's going on. The males are awesome with that crisp white edging on the fins, and the coolest part is the dad carries the eggs in his mouth, so you'll sometimes see him just chilling and not eating for a bit while he incubates.
Rhinogobius duospilus
This is one of those little stream gobies that acts like it's glued to the rocks-its pelvic fins form a suction-cup so it can hang out in flow. Males can color up really nicely and they'll claim a favorite cave/stone like a tiny bouncer, but in a well-structured tank they're super fun to watch cruise the bottom and perch.
Parachela williaminae
Parachela williaminae is one of those sleek, silvery river "glass fish" types from the Mekong/Chao Phraya systems - built for current and open-water cruising. It is not a tiny rasbora-style fish at all (it can hit around 12 cm/4.7 in), so think "active river minnow" and plan space and flow accordingly.
Parabotia banarescui
Parabotia banarescui is a Chinese botiid loach that stays low, cruises the bottom, and will wedge itself into rockwork like it was built for it. It is the sort of fish that acts shy at first, then turns into a busy, social little bulldozer once it feels secure and you keep it with its own kind.
Yunnanilus analis
Yunnanilus analis is a little bottom-hugging stone loach from China, originally described from Xingyun Lake in Yunnan. Its species name is literally about the anal fin - it has six branched anal-fin rays, which is a weirdly specific ID feature. This one is not an aquarium regular, so if you ever actually see true Y. analis for sale, it would be a pretty unusual find.
Xiurenbagrus xiurenensis
This is a tiny little Chinese torrent catfish from the Pearl River drainage - think bottom-hugging, hidey fish that wants clean, oxygen-rich water. It stays around 10 cm/4 inches and is more of a nighttime rock-and-crevice cruiser than a "front glass" pet. If you set it up like a cool, fast stream with lots of cover, it should act way more confident.
