My moor has a single small white dot on the edge of his tail fin - about
the
size of a pin head. Its not gone any bigger and the others don't seem to
have anything and all seem to be healthy so far. I've dosed with "disease
safe" but any other suggestions.? Water parameters are fine by the way.


Sorry should have said:

Nitrates are negligible - less than .03 and PH is 7 - 7.25. Tank is 45 gal
holding 3 fish - bubble eye, moor and lionhead. Only the moor seems to have
the white dot. Had it for about 4 days now. 10 - 20% water change done every
7 - 10 days. Feed is mainly high protein small pellets plus some dried
tubifex, dried daphnia and some flakes. Fed twice a day (eaten well within
the 5 min period). Filtration is fluval filter (cleaned in aquarium water
each water change). Also under gravel filter with airstone
