Gymnocorymbus ternetzi
Black skirts are those little "suit-and-tie" tetras with the dark bands and flowing fins that look way fancier than they should for how tough they are. They're super active midwater fish, and when you keep a proper group they do that tight, zippy schooling thing that makes the whole tank feel alive. Just give them enough buddies and finny tankmates they won't be tempted to nip.
Hasemania nana
These little guys are like tiny sparks in the tank-silvery bodies with those warm orange "copper" fins that really pop when they're happy and colored up. Keep them in a proper group and you'll see them cruise around together, doing that classic tetra "we're all going this way now" thing, and the males will sometimes flash at each other without it turning into real drama.
Hemigrammus ocellifer
This little tetra does a neat trick in the light-there's a shiny "headlight" spot near the gills and a glowing "taillight" at the base of the tail, so the whole school kind of sparkles as they turn. They're super chill in a group, and they look way better the bigger the shoal is and the more plants you give them to cruise through.
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.
Hyphessobrycon amandae
Ember tetras are tiny little orange "glow fish" tetras that look insanely good over a dark substrate with plants and a bit of leaf litter. They're happiest in a proper little gang, and when they settle in and feel safe the whole school starts moving like one warm, flickery cloud.
Hyphessobrycon amapaensis
This is a tiny, super sleek little tetra with a clean red stripe down the side that really pops once its settled in. It does best in a planted, slightly tinted "creek-style" setup and looks way cooler when you keep a proper group so they school and flash that line together. If you can give it soft, slightly acidic water and a calm community, its an easy fish to fall for.
Hyphessobrycon bentosi
Rosy tetras are those little coppery-pink characins that look kinda "glowy" when the light hits them right, and the males can get nice extended fins when they're settled in. Keep a small group and you'll see them do their little pecking-order sparring and flashing-nothing scary, just classic tetra drama that looks awesome in a planted tank.
Hyphessobrycon elachys
This is one of those tiny Paraguay-basin tetras that looks kind of understated until the males mature and start throwing those longer, flowy fins - then it gets really classy. Keep them in a proper little group and theyll spend the whole day hovering and cruising the midwater, looking extra sharp over dark substrate and plants.
Hyphessobrycon herbertaxelrodi
Black neons are one of those little tetras that look kinda understated until the light hits them-then that bright stripe pops and they shimmer when the school turns together. They're super chill, always cruising mid-water, and they make a tank feel "alive" without being hectic. If you keep a nice group, they get bolder and you'll see way more of their personality.
Hyphessobrycon loweae
This is a tiny Upper Xingu tetra that can glow gold in the right light, with males showing that cool elongated dorsal fin. It does best when you keep a real group and give it a calm, planted setup so it feels bold enough to come out and color up.
Hyphessobrycon pulchripinnis
Lemon tetras are one of those fish that look kind of subtle at first, then you catch the light and the whole body glows yellow with those punchy black-and-yellow fins. Get them in a proper little group and they're constantly cruising together, super active but not obnoxious. I also love how their red eyes pop when they're settled in and feeling good.
Hyphessobrycon roseus
Hyphessobrycon roseus is a tiny little phantom-type tetra from the Maroni and Oyapock river basins in the Guianas, and it looks awesome in a planted tank where the yellow-gold body and that dark shoulder spot really pop. Keep a nice group and they settle in fast, cruise the midwater together, and the males do those fun little display spats that stay pretty harmless.
