Bristlenose Pleco (Common Bristlenose)
Ancistrus cirrhosus
The Bristlenose Pleco is a small catfish with a sucker mouth, armored body, and distinctive bristles on its face, especially in males. It is primarily nocturnal and spends much of its time grazing on biofilm and algae from surfaces, making it a popular, hardy "algae-eater" in community aquariums.
Bronze Corydoras
Corydoras aeneus
The Bronze Corydoras is a charming and highly popular freshwater fish known for its peaceful nature and striking bronze coloration. It has a stout body with barbels around its mouth, allowing it to forage effectively on the substrate. Often seen in schools, this species is well-loved for its social behavior and bottom-dwelling habits.
Brown Fork-Tail Loach
Vaillantella cinnamomea
Vaillantella cinnamomea is a slim little Borneo loach with that cool forked tail and a subtle cinnamon-brown body with a dark eye stripe. It spends most of its time hugging the bottom and weaving through leaf litter and roots, then suddenly darts like a tiny torpedo when food hits the sand. Keep the tank covered tight - these forktails are famous for surprise launches.
Bunguran rasbora
Rasbora bunguranensis
Rasbora bunguranensis is a small, schooling Rasbora from Indonesia's Natuna Besar (Bunguran) Island. It stays pretty modest in size (about 8 cm standard length), so it fits that classic Rasbora vibe: active midwater cruising and happiest when you keep a proper group so they feel confident.
Busuma tilapia
Tilapia busumana
Tilapia busumana is a West African cichlid from Ghana/Côte d’Ivoire drainages (including Lake Bosumtwi). It is a pair-bonding, open-substrate spawner with biparental brood guarding.
Cahual tridentine catfish
Tridentopsis cahuali
Tridentopsis cahuali is one of those truly tiny South American pencil catfishes - think around 2 cm, basically a living sliver. It is from the Paraguay River basin, and its whole vibe is secretive micro-catfish life in warm freshwater. Real talk: there is very little hobby-grade care info out there, so I would treat it like a delicate specialty fish and plan on a species tank and careful observation.
Calabazas shiner
Aztecula calabazas
Aztecula calabazas is a tiny Mexican shiner/minnow from the Rio Panuco basin, basically a little stream fish that spends its whole life in a very small area. Its big claim to fame is how localized and rare it is - this is one of those species thats more of a conservation fish than a normal aquarium fish you see for sale.
Caohai stone loach
Eonemachilus caohaiensis
This is a tiny Chinese stone loach from high-elevation Caohai Lake in Guizhou, and it is basically a bottom-hugging little noodle that wants clean, well-oxygenated water. It is not something you will see in the trade much, but if you ever did, I would treat it like other small cool-water nemacheilid loaches: lots of cover, smooth sand, and steady filtration.
Cape Fear shiner
Notropis mekistocholas
This is a tiny, super-local North Carolina shiner from the Cape Fear River basin, and it has a weirdly long, coiled gut for a shiner because it can make a living on a lot of plant-y, detritus-type foods. In the wild it hangs around rocky and sandy pools and runs and often schools up with other minnows, plus it shifts into slower pools to spawn in late spring into summer.
Caqueta whiptail catfish
Sturisoma caquetae
Sturisoma caquetae is one of those sleek, sturgeon-bodied whiptails that just glides around like a little underwater paper airplane. It stays pretty slim and spends its time clinging to hard surfaces and grazing biofilm, so it does best in a mature, super-clean tank with good flow and oxygen.
Cardinal Tetra
Paracheirodon axelrodi
The Cardinal Tetra is a small, vibrant freshwater fish known for its striking iridescent blue and red coloring. It is closely related to the Neon Tetra but can be distinguished by the extended red stripe that runs the entire length of its body. People love keeping Cardinal Tetras in their tanks because they're peaceful and great at schooling together.
Carens barb
Enteromius carens
Enteromius carens is a small freshwater cyprinid from West-Central Africa. It is known from the Kouilou basin to the Chiloango basin (Republic of the Congo, Cabinda/Angola, and DR Congo), with a single record from the Foulakari River in the lower Congo basin. Maximum recorded size is about 3.2 cm standard length.
