The brook gobies (Rhinogobius) are as adult fishes pure freshwater inhabitants, which are found at most once in the brackish water of the lower reaches of running waters; but even this is the exception, not the rule. With 140 described species, 72 of which are generally considered valid, there is still a wide open field here for aquarists with an urge to explore. All species can be maintained well in the aquarium. When breeding, there are those Rhinogobius that have tiny larvae that grow in the sea and those that have large larvae that grow in freshwater. All species are cave spawners, the male guards the clutch until the larvae hatch. Brood care ends when the larvae swim free.
For the first time we could import Rhinogobius shennongensis from China. It originates from the Yangriwan, upper Hanjiang River, Mount Shennnong, Hubei Province. The maximum length is about 5-6 cm, males are larger than females. The sexes are most easily distinguished by the shape of the head. According to their origin, the fish are kept not too warm (18-24°C), in clear, oxygen-rich water with a good current. They are bottom fish, the males form territories. Rhinogobius shennongensis is somewhat quarrelsome; therefore possible tank mates should not be too squeamish. All common ornamental fish food is eaten, although some specimens do not like dry food. Frozen food is always accepted.
For our customers: the fish have code 453480 on our stocklist. Please note that we only supply wholesale.
