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.
Emperor tetra
Nematobrycon palmeri
Emperor tetras are those classy little Colombian characins with the dark horizontal stripe and the males' awesome trident/lyretail look. Keep a decent-sized group and you'll see the males do their little posturing displays without really hurting each other, especially in a planted tank with some shade.
Endler's livebearer
Poecilia wingei
Endlers are basically tiny little firecrackers-males stay small but flash a ton of neon color and never stop cruising the tank. They're super social and active, and if you keep males and females together you'll have babies before you've even finished tweaking the aquascape.
Eurasian Minnow (Common Minnow)
Phoxinus phoxinus
Phoxinus phoxinus is a small, fast-swimming minnow associated with cool, well-oxygenated waters. It is a gregarious shoaling fish; males intensify in colour during breeding. Note: the name P. phoxinus has historically been applied broadly across Eurasia, but the group is now treated as a species complex in which true P. phoxinus may be restricted to parts of Western Europe.
European gudgeon
Gobio gobio
The European gudgeon is a small bottom-dwelling cyprinid with a slender body, sandy-brown mottling, and distinct barbels at the corners of the mouth used to locate food in the substrate. It is an active schooling fish that prefers well-oxygenated water and a sand or fine-gravel bottom, often resting on the substrate between foraging bouts. Best kept in cool, river-style aquariums with moderate flow rather than warm tropical setups.
Forktail blue-eye (Forktail rainbowfish)
Pseudomugil furcatus
Pseudomugil furcatus is one of those little fish that never sits still-in a good way. When you keep a proper group, the males do these harmless fin-flaring "showdowns" and the forked tail + blue eyes really pop, especially in a planted tank with some open swimming room. It's a peaceful, small schooling fish from Papua New Guinea rainforest streams, and it's an easy way to add constant movement to a tank.
Glass catfish
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.
Glowlight rasbora
Trigonostigma hengeli
This is the little "orange neon line + tiny black wedge" rasbora that absolutely glows when you keep it over a dark substrate with plants and a bit of tannin-stained water. The best part is how tight they school-get a decent group and they move like one fish, super calming to watch.
Glow Light Tetra
Hemigrammus erythrozonus
The Glowlight Tetra (Hemigrammus erythrozonus) is a small, peaceful South American schooling tetra with a translucent silvery body and a distinctive iridescent orange-red stripe running from the snout to the base of the tail.
Golden otocinclus
Otocinclus affinis
Otocinclus affinis is a small South American suckermouth catfish prized for grazing soft algae and biofilm on plants, glass, and décor. It has a slender body with a dark lateral stripe and a pale underside, and it is best kept in groups where it feels secure. Although peaceful, it can be delicate when newly imported and does best in mature, well-oxygenated aquariums with plenty of natural growth to graze.
Golden pencilfish
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.
Goldfish
Carassius auratus
Goldfish are one of the most popular and recognizable freshwater fish in the aquarium hobby. They are known for their golden-orange coloration, although they can also appear in red, white, yellow, and black. Goldfish are highly adaptable and can thrive in a variety of conditions, making them a favorite among beginners.
