I own a 70 litre tank with three Ranchu fish.. One of them has since about a week developed a row of white pimples on the leading edge of the pectoral fins..
The last days I was to busy to take a close look at my tank but this morning I discovered little 1 mm. bright "hills" of darkish dots beneath the leaves of one of the plants in my tank.. when I try to get such a dot off the leave with my nail, my finger is covered with I believe 20 or so VERY small balls, the size of a sezame-seed with a dark dot in it.. the leaves are covered with about 30 little 1 mm. "hills" each (the leaves are about 20 cm.)..
now.. Can anyone tell me if these are goldfish-eggs? Sadly, my digicam is broken, so at the moment I haven`t got the possibility to put a picture on the net..
