Down Species Information
Size 710mm or 28" SL. Find near, nearer or same sized spp.
Identification Members of the genus Hemibagrus are bagrid catfishes that can attain standard lengths of up to 800 mm and are found in large rivers throughout the Indian subcontinent,Southeast and East Asia. Members of this genus have depressed heads,rugose head shields not covered by skin,a slender occipital process and moderately long adipose fins.

In life, the crystal blue eye and long, low sloping forehead identify this species which was previously known as Mystus wyckii. Due to the similarity in species name, sometimes this species is mixed up with H. wyckioides (previously known as Mystus nemerus) but H. wyckioides is a more grey colour and has a red tail fin.
Sexing Unknown, perhaps females are smaller and fuller.

Down Husbandry Information
Feeding All types of foods are taken. Young fish can be grown quickly on small meaty foods, but flakes and tablets are also taken. It is best to avoid feeding live fish at an early age - the fish will consume much more as it grows and may become picky about other foods. Larger fish can be fed earthworms, mollusks, prawns, white fish meat and pellets. Experimenting with other foods is recommended.
Furniture Inhabits lakes, creeks and rivers in the wild. Large rocks and driftwood if anything at all. These should be firmly secured in place. Heater guards are necessary, if using heater stats. External heating and filtration is a good idea. Large plants will not be eaten but again must be securely in place and of a sturdy nature.
Compatibility A lone predator, will attempt to systematically dismantle any living thing too large to be consumed outright. Some report successful combination with much larger fish, but this would require a public aquaria sized aquarium or pond, very risky in anything smaller.
Suggested Tankmates None. Try it and you'll end up with one Hemibagrus sooner or later.
Breeding Unreported in the home aquarium, probably lays huge numbers of eggs.
Breeding Reports There is no breeding report.
