TB Shrimp / The Brothers Shrimp — Asia, reported Vietnam (confirm farm locality)
Identification: TB = The Brothers Shrimp, as identified by authorized UK distributor Shrimp Cove. Social source associates TB with Hop Bui, but do not promote the personal name to canonical company identity without first-party confirmation. Vietnam country is a secondary historical attribution, not verified street/location.
Associated lines / current stock examples: Orange Bolt, Red Galaxy Fishbone Snowflake, Red Fancy Tiger, Orange Metallic Boa, Orange-base Wasp, Red/Black Blizzard and Snowfall, Orange Boa. These are associated products/contest labels, not a fully enumerated current breeder catalog or proof TB invented all these trade names.
Documented selection practice: Distributor states TB develops stabilized lines over successive generations by selective grading for pattern, color, shell coverage/clarity, health and uniformity. A breeder-run Facebook post says they are selecting shrimp for the next generation of Blizzard, with a reported Orange Boa breeder post describing 50 females and 10 males selected as breeding candidates; this is a social-post description, not a universal sex ratio, evidence of control
Galactic Shrimps / Marcin Stadnik — Poland
Identification: Marcin Stadnik, breeder associated with Galactic Shrimps (Poland), reported by competition coverage and company's own blog.
Farm/selection practices: First-party site reports over 100 tanks of about 80 L average (self-reported, current page). Its firsthand December 2024 article says under-gravel filtration (UGF) under ADA Amazonia is personally used, with the subjective observation of stable water, good shrimp health and deeper color. This is breeder experience rather than a controlled trial; UGF not universally best. Site publishes guides on substrate, shrimp-specific water preparation, shipping
Catalogued / associated lines (as viewed Oct 2026): Red Fancy Tiger, Blue Devil OE, Blue Dream OE, Bloody Mary, Pure Red Line GS Line 2, Red/Black Snowfall, Red Melting Snowfall, Blue Boa, Metallic Blue Boa, Black Fancy Tiger, Blue Panda, Hornet, Ocean Blue, Red/Advanced Black Nanashi, Red Fishbone, Blue Bolt/Deep Blue Bolt/OE Blue Bolt, Red/Yellow Eye Devil, King Kong Red Ruby, Wicked Stardust, Galactic Shrimps Red Stardust. Retail listings ≠ all in-house-created strains; li
Marcel — Netherlands; full identity UNRESOLVED
Identification: A Marcel interviewed by Shrimp Sanctuary during a Dutch breeder visit about orange-eye white-pigment Caridina; published 2025-05-14. No sufficiently corroborated surname has been established. Do not equate this person automatically with historical German contestant Marcel Wientges, with Facebook commenter Marcel Rous, or a Dutch classified listing under 'Marcel Den Helder': these may be unrelated.
Breeder-associated strain: Orange Eye (OE) White-pigment Caridina, described by video producer as an unusual breeder breakthrough and claimed first of its kind; that priority claim is attributed to the interviewer, not independently established by genetic/contest evidence.
Known technique: The source describes visiting and listening to breeder's process; no reliable numeric GH, KH, pH, temperature, soil formulation, crossing lineage or generations are independently transcribed/verified. These must remain 'not documented' instead of inventing details.
SIXI Shrimp — breeder/line label, exact country and operator UNVERIFIED
Identity: 'SIXI Shrimp' appears as breeder/source label in U.S. hobbyist Shrimp Studio posts and reseller listings. A reseller may mark stock 'Taiwan' as country of origin, but that is not reliable evidence of SIXI breeder location or citizenship. Keep country unknown until first-party farm confirmation.
Associated strains / breeder-source claims: Red Snowfall, Black Snowfall, Klein Blue / Extreme Blue Bolt, Blue/Green Boa, Blood Red Galaxy Fishbone Boa, three-band Crystal Red. A U.S. hobbyist describes Sixi Boa as showing strong snowflake-like spots, which should be a phenotype observation, not an inferred genetic marker.
Competition provenance: In posts dated September 2026, Shrimp Studio (US) reports its own entries from SIXI-related line stock, including first place and Best of Show with Red Snowfalls at a 2026 Aquashella Chicago shrimp contest; mentions a separate first-place three-band Crystal Red, Klein Blue, third-place Blood Red Galaxy Fishbone Boa. This is a line-source / entrant relationship, not evidence SIXI personally exhibited or won. Source is social/third-party; the event's off
