Ambastaia sidthimunki
This is the little "Sid" loach people fall in love with once they see a whole group doing their goofy zoomies and clicking at each other. They stay tiny but act like big loaches - always busy, always social, and way more confident when you keep them in a proper gang. Give them sand, hiding spots, and lots of buddies and they really shine.
Ancistrus cirrhosus
Ancistrus cf. cirrhosus is a small Loricariid catfish known for its sucker mouth, armored body plates, and the distinctive facial bristles (especially prominent in adult males). It is primarily nocturnal and spends much of its time grazing on biofilm and algae from surfaces, making it a popular, hardy "algae-eater" in community aquariums.
Betta albimarginata
This is one of those wild bettas that feels more like a tiny aquarium predator than a "fancy fin" betta-sleek, quick, and always watching what's going on. The males are awesome with that crisp white edging on the fins, and the coolest part is the dad carries the eggs in his mouth, so you'll sometimes see him just chilling and not eating for a bit while he incubates.
Betta macrostoma
This is the famous "Brunei beauty" wild betta - a chunky, orange-red fish with an awesome little eyespot on the dorsal fin and a big attitude-free personality (until you put two males together). The really cool part is breeding: the male is a paternal mouthbrooder, and the pair does that weird "kiss" egg transfer behavior people geek out over.
Betta splendens
Betta fish, also known as Siamese fighting fish, are popular for their striking colors and flowing fins. They are known for their territorial nature, especially males, which can display aggressive behavior towards each other.
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.
Chromobotia macracanthus
Clown loaches are those orange fish with the chunky black bands that act like total goofballs-piling into the same cave, clicking at each other, and sometimes doing that "am I dead?" sideways nap. They stay way calmer and more confident in a proper group, and once they're settled they'll spend all day cruising the bottom and sifting around for snacks.
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.
