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.
Indostomus paradoxus
This is that goofy little "freshwater seahorse"-looking fish that just kind of perches and scoots around like a tiny armored twig. Its whole vibe is slow, sneaky micropredator - once its settled in, you will catch it stalking microfoods and doing these subtle little posture displays. The big trick is feeding: they do best when you can provide lots of small live foods in a calm, planted tank.
Iriatherina werneri
This is the little rainbowfish with the ridiculous, delicate streamers - especially on the males, who love to posture and "dance" at each other in a calm planted tank. Keep them in a real group and they get way braver, cruising the top/midwater under floaters and showing off those thread-like fins. They are peaceful, but they really hate fast flow and rough tankmates that shred fins or outcompete them at feeding time.
Koumansetta rainfordi
This little goby is a tiny striped hoverer that spends its day scooting between rock crevices and pecking at the sand and micro-stuff on the rocks. In the right setup its a super chill, reef-safe character fish, but the big trick is keeping it well-fed in a mature tank so it doesnt slowly waste away.
Kryptopterus vitreolus
This is the truly transparent "glass" catfish from Thailand - you can literally see the spine and organs when its happy and settled in. The big trick is keeping them in a proper group and giving them calmer, dimmer conditions; once they feel secure, they cruise around together and look unreal in the water column.
