The fish actually seems to be resting on the bottom, which concerns me, as this is not normal behaviour. It usually indicates a gut problem of some sort.
I still am sure that the fish would definately appreciate some extra cover. He is hanging around and behind the filter as it is the only cover available in the whole tank.
As for infections and treatment, if I was certain that my water quality was good, I would consider treating the fish for internal parasites/worms. personally, I would use flubendazole, but I don't know whats available to you in India.
I wonder if the stress of losing his tankmate and being left alone for a few days etc, supressed his immune system, leaving him open to a gut infection/infestation of some sort.
