Crimson Flash Rasbora
Crimson Flash Rasbora
Crimson Flash Rasbora (Rasbora cf. patrickyapi) is closely related to Patrick's Rasbora but is traded under the 'cf.' designation — meaning 'compare with' — indicating it resembles R. patrickyapi but may represent a distinct, unconfirmed species or locality form. The 'Crimson Flash' trade name reflects the vivid red to crimson iridescence in the fins and body highlights that distinguishes this form from the standard Patrick's Rasbora.
Feeding & Care Tip: Sera Vipan Tropical Flakes and Hikari Micro Pellets make excellent daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp, Hikari Frozen or Freeze-Dried Tubifex Worms, or Hikari Vibra Bites. Feed small amounts 2–3 times daily.
From Borneo — the exact species status and locality are unconfirmed. The 'cf.' designation signals that taxonomic identity is uncertain and this fish may eventually be described as its own species. Blackwater peat swamp habitat assumed based on its close relationship to R. patrickyapi.
Keep in groups of at least 8. Soft, slightly acidic water preferred. Compatible with peaceful community fish. The crimson iridescence is most vivid in well-conditioned fish in soft water with tannin additions.
A collector interest fish — the unconfirmed taxonomic status means this may be a future new species discovery. The crimson-flash coloration distinguishes it visually from standard Patrick's Rasbora.
