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 luminatus
This little blue-eye is basically a tiny fireworks show-males flash electric blue eyes and red/orange fins and spend half the day showing off to each other. Keep them in a nice-sized group and you'll see constant "dancing" and fin-flaring in the open water, especially over dark substrate and plants.
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.
Pterophyllum scalare
Pterophyllum scalare is that classic tall, triangle-shaped cichlid that just glides around like it owns the midwater. Give it some vertical space, plants/wood to weave through, and it'll reward you with tons of personality-especially once a pair forms and starts guarding a spawn site.
Pterygoplichthys gibbiceps
The Sailfin Pleco is a large South American armored catfish known for its tall, sail-like dorsal fin and leopard/reticulated patterning over a dark body. It is a hardy algae grazer when young but quickly becomes a very large, heavy-bodied fish that produces significant waste and requires substantial filtration and space.
Pungitius pungitius
The ninespine stickleback is a small, slender stickleback with multiple short dorsal spines and a silvery to brownish body that often shows subtle mottling. Males can develop darker coloration and enhanced contrast during breeding and may become more territorial while guarding a nest. It is adaptable to cool, well-oxygenated water and is best kept with similarly temperate species rather than tropical community fish.
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.
Rhamphochromis longiceps
This is one of Lake Malawi's sleek, open-water predator haps - long, torpedo-shaped, and built to chase down smaller fish. Adults can get a cool greenish metallic sheen on the back and mature males may look more bluish-grey, plus the females are classic mouthbrooders.
Rhinogobius duospilus
This is one of those little stream gobies that acts like it's glued to the rocks-its pelvic fins form a suction-cup so it can hang out in flow. Males can color up really nicely and they'll claim a favorite cave/stone like a tiny bouncer, but in a well-structured tank they're super fun to watch cruise the bottom and perch.
Rineloricaria lanceolata
This is a slim little whiptail (a Loricariid) that spends most of its time gliding over sand and leaves, picking at biofilm like a tiny vacuum cleaner. Give it driftwood, caves, and calm tankmates and it turns into a super chill, sneaky-bottom-dweller with that awesome long whip tail and high dorsal fin.
Rohanella titteya
Cherry barbs are small Sri Lankan barbs; males intensify to deep red (especially when breeding). They’re generally peaceful and can be shy unless kept in a group, and they look best in planted aquariums with subdued lighting and darker substrate.
Sahyadria denisonii
This is that sleek "torpedo" barb with the red racing stripe and black line-built for constant cruising in the middle of the tank. They're happiest in a proper group with lots of open swim room and really clean, oxygen-rich water with some flow. Get a school going and they look like a little pack of mini river missiles.
