Surely you do not expect him to divulge this top secret info.
His scam would be over.

My possition on the issue is that you CAN, of course, have
a fish tank without changing water for a year or longer...
The problem lays in details: what tank, what animals are
kept there, how do they feel, how yellow the water is, etc.
That is why I do not doubt in the fact itself - I assume he
is telling truth: he is not changing water since January.
But I would like to know what kind of tank it is, its size, etc.
