Nemateleotris magnifica
This is that little "hover-and-dart" reef fish with the yellow face and the white-to-red fade that looks like it was airbrushed on. It'll pick a bolt-hole in the rockwork, hang in the water column facing the current, and do that cute little flag-flick with the tall first dorsal fin when it's feeling bold.
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.
Paracheirodon innesi
The Neon Tetra is a small, brightly colored fish known for its vibrant blue and red stripes that run the length of its body. It is a favorite among aquarists due to its striking appearance and peaceful nature. Neon Tetras are schooling fish that thrive in groups, adding a lively and colorful presence to any aquarium.
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.
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.
Pristella maxillaris
This is that little see-through tetra where you can kinda make out the spine inside the body, and then it tops it off with those sharp black/yellow/white fin markings and a reddish tail. Super chill schooling fish, and it's one of those rare tetras that doesn't freak out if your water isn't "perfect Amazon blackwater" 24/7.
Pseudomugil gertrudae
This little blue-eye is one of those fish that looks "cute" at first glance, then you notice the electric-blue eyes and the males flashing those spotted fins at each other all day. They're happiest in a planted, kind of shady tank with gentle flow, where they'll cruise in a loose group and do constant mini courtship displays.
Pseudomugil signifer
Pacific blue-eyes are tiny Aussie "blue-eye" fish with those unreal electric-blue eyes and a nice little shimmer when they're in a group. Give them plants, gentle flow, and a proper shoal, and the males will posture and flare at each other in this super cool, non-lethal (usually) displayy way. They'll also tolerate a bit of salt (brackish), which is handy if you're doing an estuary-style setup.
Pterapogon kauderni
Banggai cardinals just sort of hover like little underwater satellites, and the bold black bars with those long, polka-dotted fins look unreal under reef lighting. They're super chill most of the time, but once a pair forms you'll see real "fish drama," and the male will even mouthbrood the babies like a champ.
Puntigrus tetrazona
Tiger barbs are little chaos nuggets in the best way-super active, always zipping around, and they look awesome with those four bold black bars and orange fins. The big trick is keeping them in a proper-sized group so they roughhouse with each other instead of shredding a slow, long-finned tank mate's fins.
