Discus has little white splotches in its tail fin

[sushiray]

Not sure what has developed. One out of 15 has some splotchy white spots almost cloudy like in the capillaries of its tail fin.

can anyone venture a guess?

will provide test info shortly but as of 9/9 it was pH 6.6 AM/NI/NA = 0 temp at 86

can not take good pics - doesn't come out too clearly, it's too light.

thx

2nd one has one splotch in it's dorsal fin & a 3rd has a splotch in its caudal fin - same area in the capillary part of the finnage.

I know w/o pics hard to tell. but if you can imagine when a dot made by an over-inked pen on paper smears, best I can describe it.

so hope someone can make a diagnosis.

Sushi, how did you get zero nitrate? What test kit are you using? Is the tank heavily planted? Did you just do a large water change before testing?

strange right? API master kit shook for more than a minute & checked out 5min. later.

my readings since june discus tank set up
AC110 + fluval 204 + sponge filter
then switched 2wks ago
2 AC110 + sponge filter

6/28 NA=0
up to 7/19 = 5
thereafter till 9/05 = 0
today 9/17 = 2.5 (between 0 - 5)

bare bottom, no plants, always test b-4 w/c to see how good or bad I am doing. re-fill direct from tap & Prime.

on other hand, my 20gal angel tank only has 3bamboo shoots & 1/4 with thin layer of gravel & AC70 (b-4 switch was using AC110)

6/28 NA=80
7/03 - 9/06 = 40

Ahh..How often is the water change and how much water is replaced? Not strange if your tank was heavily planted or gets plenty of water changes.

at least every other day, if not daily. not planted at all. w/c is 20-30% every other day & once a week it's 75%.
