Like all Scleropages, Asian arowanas have long bodies; large pectoral fins; dorsal and anal fins located far back on the body; and a much larger caudal fin than that of their South American relative, the silver arowana, Osteoglossum bicirrhosum.
Using its pectoral fins as feet, it will slowly (but efficiently) walk from rock to rock till it hides again in the next algae "bush".
Its tail is yellow with black edges, and its pectoral fins have yellow edges. Like other tangs, these fish are omnivores. They need plenty of algae and other greens in their diet to keep them healthy, but will also eat small bits of meaty foods.
It will have sharp spines in the dorsal and pectoral fins. They have relatively small eyes for their bodies.
As its name suggests this fish may make a good catfish for an African Cichlid tank. Do not keep it with smaller fish.
They may be sexed based on the pectoral fins, which are larger in males than in females. Spawning follows a courtship ritual that includes sinuous movements back and forth by the breeding pair, sometimes lasting for a period of several hours.
In the aquarium, the white tips on the dorsal, pelvic, and pectoral fins can identify the male. The female will lay a relatively small number of eggs, which hatch in about 24 hours after fertilization.

Rays and skates tend to use their, modified, pectoral fins for locomotion in a more odd manor, that being a form of undulation or something similar to a bird flapping its wings. Their tails are designed more so for protection.
The dorsal fin is high, the first ray is strong, and on the pectoral fins it has very strong spikes. The tail has strong rays in the superior and inferior parts. Between the rays the tail is oblique. This ancistrus can reach 14 cm length.

The salinity is therefore variable, leading to the presence of fauna specific to these areas. The best-known occupant of mangroves is the periophthalmus, an amphibious fish which can develop out of water on account of the form of its pectoral fins.
