Soil/silt on bottom of pond - cleaned out last year. Water still
cloudy from extracting leaves, blanket weed etc.
Does it need cleaning out regularly - some fishponds seem to go on for
ever without cleaning.
Lots of pondweed plants etc.

black is almost always toxic water, like if they sat down on mulm that
had a lot of H2S coming out. is the pond clean on the bottom?
black spots are a sign of disease transmitted by snails.
If you got em right away take a look at the gills. dark gills = toxic
water.
