SYMPTOMS
9. Small, pure white, clearly-defined spots (about 1/4 - 1/2 dia..... of pinhead) appear on body AND finnage. (CAUTION: do not confuse with same-sized GREYISH-WHITE, blurred-edge spots appearing on finnage only - see No. 10 below). If untreated, spots slowly (6-24 hrs..) advance to cover whole body/finnage area. Fishes do not show same early sickliness as with disease 7 and may even continue feeding lightly.

DISEASE
WHITE-SPOT DISEASE - caused by ciliated protozoan (Cryptocaryon irritans - S/W Ichthyophthirius multifilis - F/W). Caused by same condition as disease No.7 above + non - irradiated livefoods.

TROPICAL FRESHWATER & COLDWATER AQUARIA
Carry out a 25%-33% partial water change with HALOEX-treated tapwater. Treat immediately with PROTOZIN. NB: In very hardwater areas the PROTOZIN should be used twice daily in the early morning and late at night.

SEAWATER AND BRACKISHWATER
Carry out a partial water change with fully matured ULTRAMARINE seawater. Treat with CUPRAZIN according to the instructions or, if invertebrates are present, treat with OCTOZIN.

GARDEN PONDS
Flush pond through slowly for 24/36 hrs. using POOLSHIELD as directed and treat with MEDIZIN P. Stop all feeding till spots disappear.

PREVENTION
Exactly the same comments apply as in disease 8. However, it should be stated here that most workers in the field of fish pathology (including the present author) believe that these protozoans are present in all bodies of water and in a resting state within most fishes but only become active when fishes are exposed to stress.
