Como identificar Comealgas Siamés

Para identificar Comealgas Siamés (Crossocheilus siamensis), observe estas características principais.

Características físicas

Formato do corpo

elongated

Coloração

The body is typically a silvery-brown to olive-brown dorsally, fading to a lighter, often whitish, ventral surface. The most prominent feature is a distinct, jagged-edged black horizontal stripe that extends from the tip of the snout, through the eye, along the lateral line, and into the caudal fin. The fins are generally translucent or slightly yellowish, lacking any prominent coloration or markings.

Tipo de escama

cycloid

Posição da boca

inferior

Características distintivas

A prominent, jagged-edged black horizontal stripe extending from snout to caudal fin., Absence of barbels, or very small, inconspicuous barbels at the corners of the mouth., Pectoral fins are held flat against the substrate when resting, unlike the slightly elevated posture of some similar species., Can change the intensity of their black stripe, making it fade when stressed or resting.

Nadadeira dorsal

Single dorsal fin, typically with 8-9 branched rays.

Nadadeira caudal

Forked caudal fin, with the black stripe extending into both lobes.

Nadadeira peitoral

Paired pectoral fins, typically held flat against surfaces.

Nadadeiras características

All fins are generally clear or slightly yellowish, lacking the distinct black and yellow markings seen in some similar species like the Flying Fox (Epalzeorhynchos kalopterus).

Dicas de identificação

1. 1

   Black Stripe

   The black horizontal stripe is the most reliable identifier. In C. siamensis, this stripe is typically jagged or irregular along its edges and extends fully into the caudal fin. In contrast, the False Flying Fox (Garra cambodgiensis) has a smoother-edged stripe that often fades before reaching the caudal fin, and the true Flying Fox (Epalzeorhynchos kalopterus) has a smooth-edged stripe that does not extend into the caudal fin, and its fins are often edged in black and yellow.

2. 2

   Barbels

   C. siamensis either lacks barbels or has a single pair of very small, inconspicuous barbels at the corners of its mouth. True Flying Foxes (Epalzeorhynchos kalopterus) have two pairs of prominent barbels, and False Flying Foxes (Garra cambodgiensis) typically have one pair of more noticeable barbels than C. siamensis.

3. 3

   Resting Posture

   When resting, C. siamensis often props itself up on its pectoral fins, which are held flat against the substrate. Other similar species may hold their pectoral fins slightly elevated.

4. 4

   Swimming Behavior

   Siamese Algae Eaters tend to 'graze' along surfaces, often resting on leaves or rocks. They are generally more active swimmers than some similar species.
