Brachyrhaphis episcopi
This is a tiny Panamanian livebearer that does best when you treat it more like a shy wild fish than a fancy guppy-lots of cover, calm vibes, and really clean water. The fun part is watching the males posture and spar while the females cruise around dropping fully-formed fry about once a month.
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.
Carinotetraodon travancoricus
This is the famous pea puffer-tiny (around 3.5 cm max) but it acts like a full-size puffer, cruising around and hunting little critters with a ton of attitude. If you give it a heavily planted tank with lots of line-of-sight breaks, you'll get to watch really cool "stalking" behavior all day.
Channa andrao
Channa andrao is one of those "how is this real?" dwarf snakeheads-tiny, super colorful, and way more personable than you'd expect from a predator. It's a mouthbrooder, hangs near the surface a lot (air-breather), and it's happiest in a plant-choked, hidey-hole setup with a tight-fitting lid because, yep, it can jump.
Chromis viridis
Blue Green Chromis are those shimmery little green-blue darts you'll see zipping around the top of a reef tank, always looking like they're catching the light just right. They're super fun in a group because they hover and cruise together, but they've got a bit of a "pecking order" thing going on if the tank's tight or the group's too small.
Corydoras aeneus
The Bronze Corydoras is a charming and highly popular freshwater fish known for its peaceful nature and striking bronze coloration. It has a stout body with barbels around its mouth, allowing it to forage effectively on the substrate. Often seen in schools, this species is well-loved for its social behavior and bottom-dwelling habits.
Corydoras habrosus
This is the tiny "salt and pepper" cory that scoots around the bottom like a little wind-up toy, constantly sifting and picking through the sand. Keep them in a real group and they get way bolder-lots of quick little dashes, little pauses, and then back to foraging. They're also one of those fish that really rewards a soft sandy bottom and calm tankmates.
Corydoras panda
Corydoras panda is a small, bottom-dwelling catfish known for its pale body with distinctive black patches over the eyes and near the tail, resembling a panda's markings. It is a peaceful, social schooling species that does best in groups and appreciates soft substrate and clean, well-oxygenated water. Like other corydoras, it forages constantly and should be offered sinking foods rather than relying on leftovers.
Corydoras pygmaeus
Pygmy cories are tiny little armored catfish that do this super-cool thing most cories don't: they'll cruise around in the midwater in a loose school instead of just shuffling along the bottom. Give them a soft sandy substrate, lots of plants to weave through, and a proper group, and they turn into nonstop little busybodies.
Corydoras weitzmani
Weitzman's cory is one of those super sleek Corydoras that looks like it's wearing a little mask-clean lines, subtle patterning, and that classic cory "busy little vacuum" vibe. The best part is watching a whole group cruise the bottom together, then suddenly zip to the surface for a gulp of air like tiny torpedoes.
Danio margaritatus
This is the little "galaxy fish" everyone stops to stare at-dark bluish body sprinkled with pearly spots and those punchy orange/red fins. They're peaceful but kinda shy, and you'll see the best color and the cutest little male sparring displays when you keep a proper group in a heavily planted tank with gentle flow.
Danio rerio
Zebra danios are those nonstop little stripey rockets that zip around the top and middle of the tank like they've had three espressos. They're super fun in a group because they chase, spar, and "race" each other without really meaning harm, and that constant motion makes the whole tank feel alive.
