Lives wild in Brunei, Cambodia, Indonesia, Laos, Malaysia, Philippines, Thailand, and Vietnam.
Introduced to China, Hong Kong SAR China, Singapore, and Taiwan.
Found in rivers, swamps, reservoirs and canals. Enters flooded forest. Feeds on small fishes, shrimps, aquatic insects, mollusks and crabs. Considered a delicacy over much of eastern Asia. Exported fishes command a high price. Maybe the largest species of the goby-like fishes.
Temperament, fin nippers, fish that eat other fish, and fish that need the same water. And what the Harmony mark in the app means.
Two aquariums from Southeast Asia: calm forest streams and peat swamps with soft, brown water, and fast mountain streams with cool, oxygen-rich water.
From the store to the tank: how to get the fish used to your water, why you should add only a few at a time, and what to watch for in the first few days.
Why new fish should live in a tank of their own for a few weeks before they move in, what you need, and what to look for.
