Silver Tip Tetra
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.

Head-and-Tail Light Tetra
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.

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.

Ember tetra
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.

Rosy Tetra
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.

Black Neon Tetra
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.

Lemon Tetra
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.
