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.
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 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 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 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.
Luminichthys noctifera
The Glow Light Tetra, known scientifically as Luminichthys noctifera, is a strikingly vibrant fish renowned for its glowing fluorescence under blue or ultraviolet light. These small, schooling fish exhibit a translucent body that often appears in shades of blue or green, with a horizontal stripe that runs along their side.
Melanotaenia praecox
These little rainbows are like living sparks-electric blue bodies with those punchy red/orange fins, and they look even better the more you keep together. They're constantly cruising the mid-water, flashing at each other and doing that classic rainbowfish "look at me" shimmy, especially when the lights first come on or at feeding time.
Microdevario kubotai
This is that tiny, glassy-yellow fish that turns into a little green highlighter once it settles into an aquarium-especially over a dark substrate and under decent lighting. They're super active mid-water shoalers, and the whole group "flashing" that neon stripe together is the main event. Keep them in a proper group and they get way bolder and look a lot more intense.
Moenkhausia pittieri
Diamond tetras are one of those fish that look kind of plain in the bag, then you get them settled in and they start throwing off this glittery, diamond-like shine when the light hits them-super satisfying to watch. They're active, always cruising around the midwater, and in a nice little school they'll do that tight, synchronized swimming thing that makes the tank feel alive.
Nannostomus beckfordi
Beckford's pencilfish is that sleek little "stick with fins" that likes to hang in the upper half of the tank at a slight angle and flash a crisp dark stripe. Keep a proper group and you'll see males do these tiny sparring/display moments (no real damage) and the whole school just looks super classy over dark substrate and plants.
