Tips Identifikasi

1. 1

   Body Shape

   Look for a slender, torpedo-shaped body, characteristic of fast-swimming, schooling fish.

2. 2

   Lateral Line

   Many Rasbora species possess a distinct lateral stripe, which can vary in color (black, iridescent blue, gold) and extent along the body. This is a key identifier for many species.

3. 3

   Fin Coloration

   Observe the color of the fins; some species have red, orange, or yellow hues, especially on the caudal and anal fins.

4. 4

   Spot/Blotch Patterns

   Check for specific spots or blotches on the body, particularly on the caudal peduncle (e.g., Rasbora trilineata with three stripes, Rasbora dorsiocellata with a dorsal ocellus).

5. 5

   Size

   Most Rasbora species are small, typically ranging from 2 cm to 10 cm in standard length, though some can reach up to 15 cm.
