Qianlabeo
Qianlabeo striatus
Qianlabeo striatus is a tiny, river-dwelling labeonin carp from Guizhou, China (Pearl River drainage) that stays under about 3.5 inches. It is the only species in its genus, and in the aquarium hobby it is basically a "data-poor" fish - you will likely be guessing a bit on care unless you can match it to its exact natural stream conditions.
Quasimodo haplochromis
Haplochromis quasimodo
Haplochromis quasimodo is a piscivorous haplochromine cichlid from the Lake Edward system, described in 2022. Species-level information available in major databases focuses on taxonomy, identification, and maximum size; aquarium-specific husbandry details are not well documented and are typically inferred from general haplochromine cichlid care.
Ram cichlid (German blue ram / butterfly cichlid)
Mikrogeophagus ramirezi
Rams are tiny little cichlids with big-time attitude (in the cutest way) and insane sparkle-those blues, yellows, and that black face bar really pop when they're happy. They're also one of the warmer-water dwarf cichlids, and they'll show off pair behavior and even spawn on flat stones if you keep the tank clean and calm.
Red-lipped Wallaceochromis
Wallaceochromis rubrolabiatus
This is a tiny West African river cichlid that stays around 2.5 inches, and the adults get that really neat reddish-purple color around the lips that gives it its name. In a tank it acts more like a shy little cave cichlid than a bruiser - give it sand, leaf litter, and a couple tight caves and it settles in and starts doing the whole pair-bond and territory routine.
Redlips Darter
Etheostoma maydeni
This is a tiny Cumberland River drainage darter with a really neat telltale feature: the red pigment right on the lips. Its whole vibe is hanging out on the bottom in calmer pools along big creeks and rivers, tucked around boulders and woody cover.
Red Neon Blue-eye
Pseudomugil luminatus
This little blue-eye is basically a tiny fireworks show-males flash electric blue eyes and red/orange fins and spend half the day showing off to each other. Keep them in a nice-sized group and you'll see constant "dancing" and fin-flaring in the open water, especially over dark substrate and plants.
Redseam dwarf cichlid
Apistogramma gephyra
A. gephyra is a tiny Rio Negro dwarf cichlid with crisp red seams on the fins and a sleek, agassizii-style body. It sticks close to leaf litter and small caves, where the female guards eggs and fry while the male patrols. Give it soft, acidic water and you get tons of color and personality from a very small fish.
Redspotted snakehead
Channa andrao
Channa andrao is one of those "how is this real?" dwarf snakeheads-tiny, super colorful, and way more personable than you'd expect from a predator. It's a mouthbrooder, hangs near the surface a lot (air-breather), and it's happiest in a plant-choked, hidey-hole setup with a tight-fitting lid because, yep, it can jump.
Red-tailed tinfoil barb
Barbonymus altus
Picture a shiny silver barb with vivid red fins and a plain red tail - no black edging - that cruises nonstop like a little river torpedo. It looks a lot like the big tinfoil barb but stays smaller, topping out around 10 inches, and really comes alive when you keep a group in a long tank with good flow.
Regan's dwarf pike cichlid
Wallaciia regani
This is one of the smaller pike cichlids, with that sleek, torpedo shape and the attitude to match - super fun to watch when it cruises and "stalks" around wood and leaf litter. It's a cave-spawning little predator that will absolutely snack on tiny fish, but compared to big pikes its size it can be surprisingly manageable if you give it space and lots of cover.
Renny's ricefish
Oryzias hadiatyae
Endemic to Lake Masapi (Malili Lakes system), Central Sulawesi, Indonesia; reported from shallow shoreline habitats and associated with shoreline root/vegetation structure. Diagnostic morphology includes a snout concavity (not unique within the genus).
Reticulated hillstream loach
Sewellia lineolata
This is the little "stingray-shaped" loach that parks itself on rocks and glass like it's magnetized, then cruises around in the current like a tiny river skate. Give it cool, super-oxygenated, fast-moving water and lots of smooth stones with biofilm, and it'll spend all day grazing and doing hilarious little dominance shuffles with its own kind.
