Triplophysa xiqiensis
Triplophysa xiqiensis is a little Chinese stone loach from cool, flowing hill-stream type water, and it lives right on the bottom picking around the substrate. It is the kind of fish that spends its day cruising and perching on rocks, so it is way more about behavior and habitat vibes than flashy color.
Yunnanilus yangi
Yunnanilus yangi is a small freshwater stone loach (Nemacheilidae) described in 2024 from Yunnan, China (upper Pearl River/Nanpanjiang drainage). Species-specific aquarium guidance is limited in the literature; husbandry is typically inferred from related small Yunnanilus/Micronemacheilus-type loaches, emphasizing clean, well-oxygenated water, cover, and small foods.
Hyphessobrycon roseus
Hyphessobrycon roseus is a small phantom-type tetra (syn. Megalamphodus roseus) from the Maroni and Oyapock river basins (French Guiana/Guianas region). It is best kept in a planted, softwater setup in a group, where males may display but are generally peaceful.
Yasuhikotakia splendida
This is a super active little botiid loach from the Mekong basin that spends its time cruising the bottom, nosing around rocks, and sorting out a pecking order with its buddies. The giveaway look is the yellow fins with polka-dot markings plus that bold dark ring around the tail base - it is a really sharp, weirdly classy pattern for a loach. Not a chill "peaceful community" fish, but in a proper group with hiding spots and flow, they are a blast to watch.
Zaireichthys flavomaculatus
Zaireichthys flavomaculatus is a truly tiny, bottom-hugging African loach catfish from the Congo basin that spends its time tucked into sand and gaps like a little river goblin. Its yellowish base color with blotchy/marbled spotting is the whole vibe, and it is the kind of fish you keep because you love oddball micro-predators and watching subtle behavior, not because it is always out front.
Noturus flavipinnis
Yellowfin madtoms are tiny, secretive native catfish from the upper Tennessee River system, and they act exactly like little river goblins - hiding under flat rocks all day and cruising around at night. The cool part is the male guards the eggs under cover, and they really appreciate clean, well-oxygenated current and a rock-and-leaf-litter kind of setup.
Hemimyzon yushanensis
This is a little Taiwan hillstream loach that lives its whole life clinging to rocks in fast, super-oxygenated streams. In a tank it does best in a "river" setup with smooth stones and lots of flow, where it will spend all day grazing biofilm and cruising the glass like a tiny underwater gecko.
Danio rerio
Zebra danios are those nonstop little stripey rockets that zip around the top and middle of the tank like they've had three espressos. They're super fun in a group because they chase, spar, and "race" each other without really meaning harm, and that constant motion makes the whole tank feel alive.
Mayaheros zebra
Mayaheros zebra is one of those Yucatan Peninsula "Mayan cichlid group" fish that looks like a smaller, striped version of the better-known Mayan cichlid. The big gotcha is that a lot of modern checklists treat "zebra" as a form/synonym within Mayaheros urophthalmus rather than a clearly separate aquarium species, so you will almost always see it discussed under the Mayan cichlid umbrella.
Hypancistrus zebra
This is the famous black-and-white striped L-number pleco (L046) from the Rio Xingu, and it really does look like a little underwater zebra. Its best traits are how cavey and secretive it is by day, then it pops out at night to hunt meaty foods - and the male will guard eggs in a cave if you ever breed them. It is not an algae-cleaner pleco, so think of it more like a tiny, warm-water, rock-dwelling catfish with attitude over caves.
Isorineloricaria spinosissima
This is a truly giant Ecuadorian pleco that can end up longer than your forearm - it is basically a river bulldozer that spends its time grazing algae and plant growth off hard surfaces. The cool (and kind of wild) part is the strong sexual dimorphism with extra-long odontodes, plus those sharp gill-area spines that can snag nets, so you have to handle it with respect.
