I bought two of these from Raymond Chan of AmazingFish in the Summer of 2016 at ~3"-4". They reached about 14" today.

Only recently have I clearly noted that they have this red fibrous structure behind their anus. Dim lighting and carelessness. At first I got super-alarmed and thought they had intestinal worms, like callamanus worms but then I saw they defecate from a pore anterior to that, that is, the anus is closer to the pelvic fin base than that structure. You can see that in the pics below. They both have this structure of about the same size and looks.

Google images show these fish to have this "brush-like thing" too, so I calmed down. Then Silurus said "That's the dendritic organ, a structure found in marine plotosids (and very few freshwater species). It apparently functions in osmoregulation." Per PCF sister thread: http://www.planetcatfish.com/forum/viewtopic.php?f=13&t=44848#p304418

They eat exceptionally well and overall look very healthy.

Another question though, how bad is their venom? Would a puncture wound really always/often result in a bad swelling and gangrene as the PCF states? Perhaps our Indian peers would know headbanger_jib headbanger_jib ?

I imagine things like these would be written about and reported in the news, Jibran?
our news reporters and media is not capable of reporting facts, will check with my friends who might have Info on these saltwater beasts

I can't speak for this species but I actually got to speak with a gentleman who had been stung many times by Plotosus lineatus/japonicus. While deep-sea fishing in Okinawa I had the opportunity to speak with the boat captain about the sting of the 'gonzui' native to the area, as everything I read in America is about how terribly painful the sting of Plotosids is. He told me that the sting of a large Plotosus was about as painful as that of a large lionfish, but not dangerous. I would imagine the sting of yours is similar, though assumption is a dangerous thing.

I digress, absolutely beautiful fish Viktor. I'm in awe of your amazing pet collection. What a stunning species!
