Snakeheads

Suborder Channoidei


Snakeheads are freshwater predatory fishes with a large robust head. There are 5 species in Singapore - 4 native and 1 introduced. The Common Snakehead (Channa striata) is the snakehead one is likely to encounter. It is generally brown in colour with faint stripes on the flanks. The Giant Snakehead (Channa micropeltes) is the largest snakehead species reaching 1 m in length. The adult has a distinctive dorsal stripe pattern. The juvenile lacks this pattern, but has the longitudinal stripe at the side of the body. It is however not a native to Singapore waters. The Black Snakehead (Channa melasoma) may appear all black or with just the fins black.

Gobies

Suborder Gobioidei


This suborder contains mainly gobies. Gobies are characterised by their disc-shaped pelvic fins, which form a sucker that allows them to hang on to surfaces. Mudskippers are gobies, which have adapted to living out of water. Gobies are generally small fish, although the Giant Mudskippers can grow up to 30 cm long.

The Marbled Goby or Soon Hock (Oxyeleotris marmorata) is a common dish on the table. It is not a True Goby (Family Gobiidae), but belong to the Family of Sleeper Gobies (Family Eleotridae), which also includes the Snakehead Gudgeon (Ophiocara porocephala).

There are a few Istigobius species in Singapore. The Goldman's Goby or Black-spotted Lagoon-goby (Istigobius goldmanni) can be told apart from the others by the double black spots on the sides of the body.

Grey Knight Goby (Stigmalogobius sadanundio) is a common goby with a black saddle on the back and small black spots on the flanks.

Mudskippers are fascinating because they can stay out of water for a period of time. They are part of the Goby family. There are more than 10 species that can be found in Singapore. The more common ones are the Giant, Blue-spotted, Gold-spotted and Yellow-spotted. The Giant Mudskipper is the largest of them all. It has a black stripe along the whole length of the body. The Blue-spotted Mudskipper has several black stripes on its body and blue spots all over, but more on the face.

Gold-spotted Mudskipper has orange spots all over its body. Yellow-spotted Mudskipper has yellow spots all over the body and the second dorsal fin has a black stripe in the middle.

Bearded and Elongate Mudskippers both have a longish body, but the former has a bluish belly and a tall dorsal fin when raised.

All Cichlids in Singapore are non-native. The most infamous being the luohan, which is a cultivated hybrid of various species of cichlids. Others like the Common Tilapia (also known as Mozambique Tilapia) and Green Chromide are also commonly seen in canals and rivers.

These fish have a flat disc-shaped body. The most commonly encountered species in this suborder is the Spotted Scat. Batfish are distinguished by the hump on the forehead that is in-line with the eyes. Rabbitfish have spines on their fins, but people still like to eat them. The Chinese name translates literally to "white-bellied fish".
