Dark-bodied tetras and small schooling fish swimming among purple aquarium plants and pale driftwood

Life observed
underwater.

Aquatics extends the cabinet below the waterline: a record of residents, environments, behavior, and care.

Six organism records now span freshwater and marine life, with identifications kept as exact—and as qualified—as the photographs allow.

Six records,
properly filed.

Each record pairs a representative portrait with the visual traits used for identification. Domestic lineages, branded strains, and look-alike marine species stay qualified where a photograph cannot support a narrower claim.

AQ–01

Gold-dust molly

Poecilia cf. sphenops · domestic strain

A domestic short-fin molly with a yellow ground color and irregular black marbling. Commercial fancy-molly ancestry is not fully traceable, so the identification is recorded conservatively.

Record type
Freshwater resident
ID traits
Yellow ground · irregular black marbling
Black skirt tetra in side profile, showing two dark vertical bars and a broad black anal fin against a blue aquarium background
AQ–02

Black skirt tetra

Gymnocorymbus ternetzi

A high-bodied South American tetra recognized by two dark shoulder bars and its broad, dark anal ‘skirt.’

Record type
Freshwater resident
ID traits
Two shoulder bars · broad anal fin
Juvenile bala shark in crisp side profile, with a silver body, deeply forked tail, and black-edged fins
AQ–03

Bala shark

Balantiocheilos melanopterus

A juvenile Southeast Asian cyprinid—not a true shark—showing a silver body, deeply forked tail, and distinct black fin margins.

Record type
Freshwater resident
ID traits
Silver body · black-edged fins
Neon tetra in side profile, marked by an iridescent blue stripe and a red band across the rear half of its body
AQ–04

Neon tetra

Paracheirodon innesi

The iridescent blue lateral stripe and red band restricted to the rear half distinguish this species from the cardinal tetra.

Record type
Freshwater resident
ID traits
Blue lateral stripe · rear-half red band
Dense colony of green star polyps extending slender fluorescent-green tentacles from aquarium rock under blue-purple lighting
AQ–05

Green star polyps

Briareum sp.

An encrusting colonial octocoral forming a dense field of fluorescent-green, eight-tentacled polyps. Identification is retained at genus because separating Briareum species depends heavily on microscopic sclerites and specimen provenance.

Record type
Marine invertebrate
ID traits
Eight-tentacled polyps · encrusting mat
Original Sea-Monkeys aquarium positioned beside a bright window, with translucent brine shrimp visible in the water
AQ–06

Original Sea-Monkeys

Artemia sp. · branded captive strain

A small captive colony of brine shrimp raised from dormant cysts. The animals first appeared as translucent nauplii with constant, jerking movement before developing into visibly shrimp-like juveniles.

Record type
Brine-shrimp colony · established August 2026
ID traits
Translucent body · rhythmic swimming appendages

Three supporting views,
one continuous archive.

These photographs reinforce records already in the index. They are filed as supplementary plates, preserving both the images and the distinction between a new photograph and a new resident.

An anatomical close-up filed against the existing resident record rather than counted as a second animal.

Original Sea-Monkeys

Artemia sp.

A close observational plate making the otherwise minute animals legible within their branded aquarium habitat.

Three aquaria,
each kept in view.

The collection is also organized by habitat. Each system record pairs an overall view with a closer detail, keeping scale, layout, and the surrounding equipment legible.
