Size 150mm or 5.9" SL. Find near, nearer or same sized spp.
IdentificationDiffers from the two other Liobagrus species endemic to Korea in the following ways: L. andersoni has upper and lower jaws of equal length, generally lighter color and occurs in waters further north than L. mediadiposalis whose range is restricted to the Nakdong River and its tributaries. L. andersoni differs from L. obesus by generally appearing longer and thinner. More importantly, the number of spines on the pectoral fins increase in number with age to 3-5 while the spines on L. andersoni decrease as the fish ages to 1 or 2.
SexingMales have broader heads. Females are plumper during the breeding season which in the wild is May to June.
General RemarksUse caution when handling any Liobagrus species. Their spines inflict painful gashes.

Temperature16.0-25.0°C or 60.8-77°F (Show species within this range)
Other ParametersFound in temperate waters, this species can withstand temperatures considerably lower and higher than shown for limited periods of time. As the common name suggests, these fish are found in fast moving waters in nature. These can be imitated in the aquarium but are not necessary as normal filter outflow and aeration make an acceptable current for these fish.

FeedingFeeds on small fish and invertebrates in the wild. Adapts readily to prepared food. Nocturnal in nature, in captivity they soon learn to come out anytime food hits the water.
FurnitureProvide plenty of large stones and gravel. Make sure that the stones are well set in the substrate as the fish will excavate caves beneath them. They prefer to hide under larger stones at least 30cm in diameter. Smaller stones will likely be ignored as will artificial caves. Plants are not necessary but floating plants are useful as they dim the lighting.
CompatibilityMay be kept in groups in a species tank. Pushing and head butting will occur but are harmless. If kept in a group, be sure to provide a large stone for each fish. They do not share burrows in nature with others of their kind.
Suggested TankmatesMay be mixed with any cold water species except for the smallest fish which it may see as food. Fish that occur naturally in it range and that make ideal tankmates include Bitterlings (Rhodeus spp.), Zacco platypus, Phoxinus phoxinus and many coldwater loach species.
BreedingSame as for genus. Not difficult if provided with seasonal temperature changes, moving water and a choice of breeding spots.
