Size 700mm or 27.6" SL. Find near, nearer or same sized spp.
IdentificationMembers 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.
SexingUnknown, perhaps females are smaller and fuller.

Jump to next section Husbandry Information
FeedingAll 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.
FurnitureInhabits 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.
CompatibilityA 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 TankmatesNone. Try it and you'll end up with one Hemibagrus sooner or later.
BreedingUnreported in the home aquarium, probably lays huge numbers of eggs.
