Parosphromenus linkei
This is one of those tiny, dark little gouramis that looks kind of understated in a store tank... until it settles in and the male starts flashing those deep reds and blues with the fancy fin edging. They're shy and a bit secretive, but when you keep them the way they like (soft, acidic, calm), they turn into these surprisingly bold little show-offs around spawning time.
Pelvicachromis pulcher
Kribensis are one of those dwarf cichlids that pack a ton of personality into a small fish-especially once they pick a cave and start acting like proud homeowners. The female's purple/red belly when she's in breeding mode is the real show-stealer, and the pair will do seriously impressive parent-care if they spawn.
Pelvicachromis taeniatus
P. taeniatus is one of those West African dwarf cichlids that'll act totally chill most of the time, then flip the switch into "serious cave owner" the moment it wants to spawn. The fun part is the local color forms ("Nigeria Red", "Moliwe", etc.) and the pair-bonding-when they settle in, you really get to watch a little cichlid soap opera play out around their cave.
Perca fluviatilis
The European Perch is a predatory freshwater fish recognized by its olive-green body, dark vertical bars, and bright red/orange pelvic and anal fins. It is an active hunter that can grow quite large and is best suited to coolwater, spacious aquariums with strong filtration and plenty of cover.

Petitella bleheri (syn. Hemigrammus bleheri)
This is the rummy-nose with the really "full-face" red that runs back past the gill plate, plus that crisp black-and-white tail that flashes when the whole group turns together. When they're happy and the water's clean, they school tight and look like one living fish-when they're stressed, that red head fades fast, so they're basically your tank's mood ring.

Petitella rhodostoma (Ahl, 1924) (formerly Hemigrammus rhodostomus)
This is the classic rummy-nose tetra-the one with the bright red "nose" and the crisp black-and-white tail that flashes when the whole group turns together. They're tight-schoolers, so a bigger group in a longer tank is where you really get that synchronized, hypnotic swimming. The red face also doubles as a little "health meter" since it tends to fade when they're stressed or water quality slips.

Petitella rhodostoma (syn. Hemigrammus rhodostomus)
This is the classic rummy-nose tetra - silver body, a solid red "face," and that crisp black-and-white tail that flashes when the whole group turns at once. The red nose is a legit mood ring for water quality and stress, so when they are happy and stable, they look incredible in a tight school.
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.
Poecilia reticulata
The Guppy is one of the most popular freshwater fish among aquarium enthusiasts due to its colorful appearance and lively nature. These fish have a wide range of vibrant colors and tail shapes, making them a visual delight in any aquarium. Guppies are known for their peaceful temperament and ease of care, making them ideal for both beginner and experienced fishkeepers.
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.
Poecilocharax weitzmani
Poecilocharax weitzmani is one of those tiny blackwater oddballs that acts more like a little darter than a typical tetra - it hangs low, darts between cover, and the males can get pretty showy with fin-flares. The really cool part is they are cave breeders with male brood care, which is not what most people expect from a small characin. Give them very soft, acidic, super-clean water and lots of leaf litter and hidey holes, and they settle in and start showing their best colors.
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.
