When growing up in the north bay area of SFO - Mom and Dad had a Fish store
for a year or two maybe more. We had discus fish and they were salt water beauties.
Vertical disk fish with nice colors.

Mom and Dad converted them to fresh water in about a year. Slowing replacing water
with fresh. If not enough salt, the fish would float canted or on the top. Thus
the speed of replacement was determined.

My thoughts if they were in the keys and lived in shallow water -
they might take brackish water. The brackish is from heavy rain and runoff.

They might be beautiful for a tank. Have several. They might be fish killers also.
Killing a $200 fish might bring dumping.

Dumping is complex. If a dead fish - flush away. If a shell - won't flush all
that well...
Trash is a killing zone - tender hearts might dump in a lake. The like, IIRC,
contains a
fair amount of lime that is dissolved from the natural deposits. The cone might
be able
to survive and maybe multiply if there were several - in the 'brackish' like water.

I don't doubt your findings at all. They are the normal findings. An inland lake in
limestone country just North of Forth Worth, Texas is a stretch from normal.
