Tag: Damselfish (Pomacentridae)

With approximately 360 species within around 19 genera, the Damselfish and Anemonefish/Clownfish are among the most numerous and popular small fish found in local waters.

Although many are easily recognised by their bright colouration, there are a few, less colourful species which tend to go almost unnoticed.

Most local species live in shallow water, in close proximity to coral reefs, although a few species can be found on sand/gravel substrates at depths greater than 30m at the offshore sites such as Sail Rock.

Members of the Anemonefish/Clownfish subfamily Amphiprioninae live in a symbiotic relationship with certain species of Sea Anemone (Actiniaria).

This section will include species from the subfamilies Amphiprioninae, Chrominae and Pomacentrinae. The 4th subfamily Lepidozyginae is not included as it does not occur locally.

Although most Damselfish are closely related with coral reefs, there are a number of species which are Benthic by nature. For this reason i have created a separate gallery specifically for the "Benthic" Damselfish species

Lagoon Damselfish (Hemiglyphidodon Plagiometopon)

This Lagoon Damselfish (Hemiglyphidodon Plagiometopon) was reasonably easy to get in frame as it was so busy attacking the camera at the time!!

Not content with viciously biting me on the thigh as i swam innocently by, it proceeded to head-butt, and even tail-butt the camera lens by backing into it repeatedly...

Palechin Moray Eel (Gymnothorax Herrei)

In this shot taken at Sail Rock, Koh Phangan, a little Palechin Moray Eel (Gymnothorax Herrei) is being moved along by a group Regal Demoiselles (Neopomacentrus Cyanomos).

This photo of a Palechin Moray Eel (Gymnothorax Herrei) with a pair of Regal Demoiselles (Neopomacentrus Cyanomos) gives an excellent impression of just how small this species is in comparison to its locally occurring relatives.

In this photo, from Sail Rock, a group of juvenile Regal Demoiselle (Neopomacentrus Cyanomos) are "mobbing" a wandering White-Eyed Moray Eel (Siderea Thyrsoidea).

Regal Demoiselle (Neopomacentrus Cyanomos)

In this photo, many of the traits that are common within the local population of Regal Demoiselle (Neopomacentrus Cyanomos) are clearly visible, namely:

The orange-coloured "ear-spot"
The neon blue fin margins
The white mark at the rear of the dorsal fin
The pale, blotchy markings which may be related to nesting activity

Regal Damselfish (Neopomacentrus Cyanomos)

Regal Demoiselle (Neopomacentrus Cyanomos) can often be found darting in and out of disused oyster shell, which they use for protection and also as a safe place to lay their eggs, as the individual in this photograph was doing at the time (the eggs are the tiny brownish dots inside the shell).

A Pink Anemonefish (Amphiprion Perideraion) attentively guarding its clutch of eggs which are attached to the rock.
Usually the eggs would be hidden beneath the protective tentacles of the Magnificent Anemones (Heteractis Magnifica), but on this occasion a strong current meant that the eggs were exposed.
