Hi all, thanks for the reply.
I have been maintain the ammonia, nitrite, and nitrate levels. The water tested out to be very good.
They are not moving at the bottom of the tank sitting on the gravel, dont' feel like to move at all.
One of them have black underside, another one have...
bump... puffers still suffering...
salt doesn't work, both fresh and ocean salt.
Ick Guard doesn't work either... Maybe i should try other medicine?
:-(
I have 3 of these in my fresh water tank. After the first one died 2 weeks ago, one of the other two is not willing to eat, and the color is turning so dark, almost like black. :-(
Since puffers are highly intelligent fish, i bet it might feel sad because one of his buddy is dead? :/
Or is...
