Corydoras pygmaeus - One of the tiniest corydoras species, topping out around 2-3cm. These little schoolers spend much of their time mid-water rather than glued to the substrate like most corys, making them a lively addition to a nano community tank.

Corydoras hastatus - Similar in size to the pygmy cory, with a distinctive dark spot at the base of the tail. Another mid-water schooler, best kept in good numbers where their constant, gentle activity really stands out. 

Corydoras metae - Named for the bold black "mask" marking across its eyes. This small cory grows to around 5 cm and spends much of its time foraging along the substrate. Best kept in a group of 6 or more.

Danio margaritatus - A tiny, jewel-like fish with a deep blue-black body scattered with pearly spots, and orange-red fins edged in black on males. Shy but stunning in a densely planted nano tank, and a species I've had great success breeding.

Pseudomugil luminatus - A striking nano species, growing to around 3cm, known for the fiery red-orange colouring and neon blue stripe along its body — especially vivid in mature males. Best kept in a small group in a well-planted tank with gentle flow.

Pseudomugil furcatus - A slightly larger pseudomugil with a distinctive forked, yellow-tinged tail. Active and outgoing for a blue-eye, doing well in small groups in a planted tank with open swimming space.

Pseudomugil mellis - One of the smallest pseudomugils, reaching barely 2.5cm, with a soft honey-gold wash over a delicate, almost translucent body. A quiet, peaceful nano fish that does best in soft, tannin-stained water with dense planting. Australian native.

Marosatherina ladigesi - A larger, elegant rainbowfish from Sulawesi with a silvery body and a bright lime green eye that really stands out in a planted tank.  Best kept in a group. This is an active, showy species.  Males flare their beautiful fins to attract females.

Melanotaenia maccullochi - Native to Australia this is a compact rainbowfish, popular for its calm temperament and schooling nature. Grows to 4-6 cm.  A great community fish for a nano to medium planted tank, and reliably easy to spawn given fine-leaved plants or a spawning mop.

Pseudomugil gertrudae (Etty Bay) - One of the smaller pseudomugils I keep, growing to 3-4cm — a real nano species, best suited to a well-planted tank with plenty of cover. Males colour up beautifully and are constantly flaring their showy spotted fins.

I've been breeding these in a dedicated spawning tank with a spawning mop.  They deposit eggs daily.  Fry are tiny but not too difficult to raise on powedered foods and microworm.

Neolamprologus multifasciatus - The smallest of the Tanganyikan shell-dwelling cichlids, barely reaching 4cm. These charming little fish live in and around empty snail shells, forming small colonies with fascinating social behaviour. A completely different keeping style to the rest of the fish room — well worth it for the personality alone.
