Coloration

Distinctive alternating bands of bright yellow to orange and dark black to brown. The number and width of bands can vary slightly between individuals and species within the genus. The fins are typically translucent with some dark pigmentation.

Scale type

ctenoid

Mouth position

superior

Distinctive features

Four to five prominent black bands on a yellow to orange body., Two dorsal fins, the first spiny and the second soft-rayed., Pelvic fins fused into a suction cup-like disc.

Dorsal fin

Identification Tips

1. 1

   Coloration

   Look for the characteristic alternating black and yellow/orange bands. The number and intensity of bands can help distinguish from other Brachygobius species.

2. 2

   Size

   They are very small fish, typically not exceeding 4 cm (1.6 inches) in total length.

3. 3

   Pelvic Fins

   Observe the fused pelvic fins forming a suction cup, a definitive goby characteristic, which they use to cling to surfaces.

4. 4

   Behavior

   Their typical behavior of perching on surfaces and darting short distances is also a good indicator.
