Zamboanga priapiumfish
Neostethus zamboangae
Neostethus zamboangae is a tiny priapiumfish (family Phallostethidae) native to the Philippines, known for males having a reproductive/copulatory organ located under the chin/throat region; it occurs in freshwater and brackish habitats.
Zebra Danio
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.
Zebra pleco
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.
Zebra sole
Zebrias crossolepis
Zebrias crossolepis is a small marine sole with bold zebra-like bands, the kind of flatfish that spends its life glued to the bottom and trying to vanish into sand. It is a subtropical, demersal species from the northwest Pacific (reported from Guangdong, China) and tops out at around 14 cm standard length, so it stays pretty compact for a flatfish.
Zonatus sand catlet
Zaireichthys zonatus
Zaireichthys zonatus is a tiny little Congo River loach catfish that lives in fast, rocky water - it is one of those blink-and-you-miss-it micro predators. In an aquarium it is all about flow, oxygen, and lots of rock crevices, and the coolest part is watching it wedge itself into cracks and scoot around the bottom like a miniature river goblin.
