SYMPTOMS
10. In early stages (first 24 / 48 hours) fishes shows signs of extreme skin/gill irritability, continually scratching and scraping on rocks etc., and "flicking" the pelvic and dorsal fins against the side of the body. However, unlike diseases 8 and 9 (which can share the same symptoms of skin irritation sometimes), this condition never causes an increase in breathing rate until the fish, after several days / weeks without treatment, is approaching death, and rarely are the near microscopic parasites noticeable as spots on the body, although they can sometimes be seen as blurred spots on fins.

DISEASE
FLUKES - external and internal "worm" parasites belonging to classes Trematoda and Cestoda species in the family Dactylogyridae parasitise the gills and digestive tract. The family Gyrodactylidae parasitise the body and finnage. Cestodes parasitise the internal digestive tract.

TROPICAL FRESHWATER & COLDWATER AQUARIA
Carry out partial water change and treat with STERAZIN (see special notes below). Stop all feeding till symptoms disappear and "spring clean" filter bed.

SEAWATER AND BRACKISHWATER
Carry out partial water change with matured ULTRAMARINE and "spring clean" filter bed at same time. Treat with STERAZIN (see below) and reduce or stop feeding.

GARDEN PONDS
Flush pond through gently for 24/36 hrs. using POOLSHIELD as directed and carry out a full course of STERAZIN P treatment. Reduce feeding.

PREVENTION
Maintain a much higher standard of aquasystem hygiene, paying particular attention to filter cleanliness and avoiding overfeeding. Always stir up filter-bed before siphoning off old aquarium water when carrying out a partial water changes. Never use non-irradiated seafoods, Daphnia, Tubifex, bloodworm, mosquito etc. Marine only - never use natural seawater or unsterilized decor objects from the beach. Above all - carry out routine STERAZIN/P prophylaxis at least once per month on all systems.
