7. Rapid loss of body weight - often despite good appetite, leading
to vertigo (loss of balance) and abnormal swimming pattern, (CAUTION
these symptoms can be confused with same symptoms produced by physical
or pressure damage to swim- bladder if present). Early symptoms later
deteriorate to ulceration and fin damage probably as a result of secondary
bacterial infections on damage sites caused by loss of balance. Finally
if untreated, the spleen, liver kidneys and brain become infected, "Pop-eye"
develops and in the last few hours, breathing rate increases to 100+
GB/min. In early stages of infection wrasse species may lose ability
to close mouth.

until respiratory rate falls to a normal 60-90 GB/min. Stop all feeding
until symptoms disappear.
diseases are extremely difficult to treat - no doubt due to the facts
a) they are essentially diseases of the internal organs i.e. spleen,
brain, liver, etc., which are difficult to reach with medications, and,
b) apart from disease 6 (Saprolegnia), there are no easily-seen external
symptoms until the disease is already well advanced.
The key to successful avoidance however is undoubtedly stated in the
"type of disease" column above, i.e. keep the system scrupulously clean
at all times. Never overfeed, use the Nitrate, Nitrite, Ammonia, pH
and Hardness test kits to ensure that water management, and water chemistry
are always maintained within optimal limits. In short - keep stress
to a minimum so that the time bomb ticks quietly away until your fishes
cheat it by dying of old age.
