|Common Names||Fossil Catfish
Gællesæk-ålemalle (Denmark), Liver Catfish, Scorpion Catfish, Stinging Catfish
|Type Locality||Tranquebar [Tharangambadi], India.|

|Synonym(s)||Heteropneustes microps, Saccobranchus fossilis, Saccobranchus microcephalus, Saccobranchus microps, Saccobranchus singio, Silurus biserratus, Silurus fossilis, Silurus laticeps, Silurus singio|
|Pronunciation||foss ill iss|
|Etymology||Heteropneustes: From the Greek heteros, meaning other and pneo, meaning to breathe; in reference to the ability of the fish to utilize atmospheric oxygen.|
|Size||300mm or 11.8" SL. Find near, nearer or same sized spp.|
|Identification||Heteropneustes fossilis can be differentiated from H. kemratensis by having lesser anal fin rays.|
|Sexing||Male has a thinner ventral line due to the stockier shape of the female.|
|General Remarks||Burgess' Atlas wrongly labels H. microps as H. fossilis in the colour plates section, but shows H. fossilis correctly in the preceding black and white text. Some references mention the rarer Sri Lankan species H. microps. This species, which purportedly differs in that the anal and caudal fins are joined in H. microps and distinctly separate in H. fossilis, is currently considered a junior synonym. The albino form is very, very rarely available to the aquarium trade.|

|IUCN Red List Category||Least Concern, range map and more is available on the IUCN species page. Last assessed 2019.|
|pH||6.0 - 8.0|
|Temperature||21.0-25.0°C or 69.8-77°F (Show species within this range)|
|Other Parameters||Hardness up to 30 °dGH with good filtration made necessary by this fishes voracious appetite. Generally an undemanding, hardy species.|
|Feeding||Will eat all prepared foods, feeder fish are not required. Larger adults will require larger foods such as earthworms and frozen prawns. Can be trained to accept large cichlid foods from the water surface.|
|Furniture||Typical medium size catfish set-up with plenty of swimming space for feeding and night time activity. A choice of shady retreats should be available for the fish during the day.|
|Compatibility||Only sensibly housed with fish that cannot be eaten and are active swimmers. Fish that rest or are slow swimmers are "buzzed" by this catfishes nocturnal prowling. Enjoys the company of it's own kind.|
|Suggested Tankmates||Large barbs and similar, Asian fish. Generally, medium sized active fish.|
|Breeding||A sticky cluster of yellow-green eggs are laid in pits in the aquarium substrate. Both parents tend the clutch, fanning the pit to ensure water circulates around the eggs. Care continues well after the fry emerge. The fry grow rapidly and can attain lengths of greater than 80mm in a matter of months.|
|Breeding Reports||There is no breeding report.|
