Tis true, I have seen a single adult male Satan-fin relentlessly harrass various
other cyprinids in tanks as large as a 55 gallon.

I cannot put more than three lineolatus in heavily planted 30 gallon tank. In the
wild, the male of the species supposedly controls areas of up to 8ft in diameter.
Since their foraging is mainly limited to the surface, they take up as much of the
upper water column as possible. In my aquariums, I have seen them harrass other
topwater species such as Gambusia to the point of exhaustion.
