Black Angel ブラックエンゼル
Verified source
Exact TOA / Fukuoka auction record with exact listing photos. The primary listing credits Tsukushi Medaka as creator; Aquapedia preserves that as listing attribution rather than upgrading it into independently proven lineage.

Shining Sun シャイニングサン
Verified source
Exact TOA / Fukuoka listing matched to the explicit strain name with exact listing photography. No unrelated look-alike is used as a substitute.

Shiva シヴァ
Verified source
Exact Fukuoka / SMYKA auction record. Standard-fin males and real-longfin females are listing-specific observations, not a universal statement about every fish sold under the name.
- Evidence
- Exact named listing

Yoru / Night 夜
Photo not verified
Mimu Medaka’s official account supports the name and new-work reference, but an indexed exact photo clearly naming and showing Yoru has not been verified. A similar fish will not be substituted.

03Caridina designer lines
Caridina
Galaxy Fishbone Taiwan Bee × Pinto material
Verified source
High-confidence research attributes development to Skyfish Aquatic in Taiwan, with development dated to 2015 and commercial release to 2016.
- Origin
- Taiwan
- Release
- 2016
Black King Kong Caridina only
Disputed
Taiwan origin is strongly supported, but the named original breeder and exact parentage remain unresolved across conflicting early accounts.
- Origin
- Taiwan — strong
- Creator
- Unresolved
Orange Boa orange-based Boa
Established line
Current Singapore and Germany lines are documented. KW Shrimps is documented as breeder/source for one Singapore line, but the generic first creator of Orange Boa remains unresolved.
- Current lines
- Singapore / Germany
- First creator
- Unresolved
Red Devil OE orange-eye Caridina
Research watch
A specialist source explicitly reports that the first breeder and location are unknown. Aquapedia therefore does not invent a Taiwan, Japan, Europe, or named-breeder origin.
- Trade status
- Established
- Creator
- Unknown
Nanashi OE competition-confirmed 2026
Research watch
A 2026 competition confirms the line in the hobby. Alexander Brunck bred the cited winning set; that proves breeder-of-that-set, not original creation of Nanashi OE.
- Existence
- Competition confirmed
- Creator
- Unresolved
Metallic Purple OE + Red Bolt OE current Germany breeding
Current line verified
Current German breeding is documented for both lines, while original creator attribution remains unresolved. Current breeder evidence is not rewritten as historical origin evidence.
- Current breeding
- Germany
- Original creator
- Unresolved
Rare-line watchlist names awaiting stronger evidence
Research watch
Metallic Purple Nanashi, Black Snowflake, Red Snowflake, Blue Snowfall, Red Wasp, and Hornet remain unresolved. Blue Snowfall is not auto-mapped to HWA Galaxy Snowfall without pedigree evidence.
- Rule
- No name-only merges
- Status
- Evidence pending
04Anchialine Hawaiʻi
Opae Ula
Halocaridina rubra population structure
Verified science
Current published work recognizes 15 genetic groups. This is a population-genetic count—not 15 consumer strains or 15 named color morphs.
- Count
- 15 genetic groups
- Meaning
- Not retail morphs
Confirmed native islands range evidence
Verified science
Strong locality records confirm Hawaiʻi Island, Maui, Kahoʻolawe, Molokaʻi, and Oʻahu. Popoiʻa / Flat Island is an Oʻahu sublocality, not a separate high-island lineage.
- Confirmed
- 5 high islands
- Watch
- Kauaʻi / Lānaʻi / Niʻihau
Red ↔ clear range documented phenotype
Verified science
Published observations document deep red through pale pink and near-translucent animals. Common-garden differences support a lineage/genetic component, while direct heritability of specific color states has not been established.
- Phenotype
- Documented
- Heritability
- Not directly proven
Maunalua South Oʻahu genetic group
Verified science
Maunalua is a recognized genetic group within the South Oʻahu lineage and is distinct from ʻEwa. Locality/genetic groups remain separate from hobby color-line naming.
- Type
- Genetic group
- Region
- South Oʻahu
Captive spawning evidence controlled population
Verified science
A captive spawning population was maintained at 23–25 °C, 18–20 ppt salinity, and 12h light : 12h dark; about 23% of females spawned in the cited work. These are documented study conditions, not declared universal optima.
- Temperature
- 23–25 °C
- Salinity
- 18–20 ppt
Brooding + larval development life-history evidence
Verified science
Sources support roughly 27–30 days of brooding, with reported fecundity ranges that vary by study, and about 29 days in the water column. Development includes four zoeal stages plus a mysis stage before settlement.
- Brooding
- ~27–30 days
- Larval phase
- ~29 days
Long-term research husbandry nearly 14 years
Verified science
One long-running research system used about 15 psu artificial seawater, 24 °C, a 12:12 light cycle, porous volcanic rock, and microbial/microalgal grazing, with reproduction occurring consistently but sporadically.
- Research salinity
- 15 psu
- Temperature
- 24 °C
What science does not establish parameter caution
Research watch
No controlled source in the reviewed set establishes one universal pH, GH, KH, or TDS breeding optimum. Adult tolerance extremes are also not breeding recommendations.
- Do not infer
- Tolerance = optimum
- Gap
- pH / GH / KH / TDS
Alpha Opae Metabetaeus lohena
Verified science
Alpha Opae is a distinct species, not an Opae Ula morph. It is an anchialine snapping shrimp in Alpheidae, documented from Hawaiʻi, Maui, and Oʻahu, with a confirmed non-Hawaiian locality on Rapa Nui.
- Species
- Metabetaeus lohena
- Relation
- Not H. rubra
Alpha Opae captive breeding cycle unresolved
Research watch
Captive attempts in Hawaiʻi reached the fourth larval instar but did not complete the juvenile cycle. Exact salinity, temperature, larval diet, flow, transition, and other captive-breeding optima remain unresolved.
- Larvae
- Planktotrophic evidence
- Full captive cycle
- Not established
