How to Identify Bumblebee Catfish

To identify Bumblebee Catfish (Pseudomystus siamensis), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Distinctive pattern of broad, irregular black bands alternating with bright yellow to orange bands across the body. The intensity of the yellow/orange can vary. The fins often have similar banding or are translucent with dark rays.

Scale type

none

Mouth position

terminal

Distinctive features

Four pairs of barbels (one maxillary, one nasal, two mandibular), Adipose fin present, Strong, serrated spines in the dorsal and pectoral fins, Small eyes

Dorsal fin

Short-based, with a strong, serrated spine and 6-7 soft rays, followed by a well-developed adipose fin.

Tail fin

Forked, with rounded lobes.

Pectoral fin

Well-developed, with a strong, serrated spine and several soft rays.

Distinctive fins

The adipose fin is relatively large and distinct. The pectoral and dorsal spines are capable of inflicting a painful sting.

Identification Tips

1. 1

   Coloration

   Look for the prominent black and yellow/orange banding pattern across the body. This is the most defining characteristic.

2. 2

   Barbels

   Observe the four pairs of barbels around the mouth, which are characteristic of many catfish species and aid in foraging.

3. 3

   Adipose Fin

   Note the presence of a distinct adipose fin, a fleshy fin without rays located between the dorsal and caudal fins.

4. 4

   Spines

   Identify the strong, serrated spines in the dorsal and pectoral fins. These are a key feature of Bagridae catfishes.
