new purchase potter angelfish up the lorry.
the rest seems fine.
my observation: dwarf angelfish does not tolerate hypo as well.
symptom of death: disorientated, swimming upside down, bloated belly
i suspect could be nitrite poisoining. what do you guys think?
been using 5-1 test strips, will purchase a nitrite test kit today to confirm.
as a result, i raised the salinity from 1.008 to 1.0095.
