I would highly doubt it is neascus. Neascus looks like smaller more defined dots of black...almost like a black version of ich. I highly doubt it is this because of the life cycle of Neascus. It's really interesting...the adult parasites are actually found in birds such as herons and look like little worm things. The parasites eggs are released into the lake from the bird. The parasite eggs actually are consumed by snails where they hatch and break from the snail. THen the newly hatched parasite swims around till it finds a fish and burries into the fish. This causes black dots wherever it burries. Then another bird comes along and eats the fish and the cycle contines. Crazy huh!? I seriously doubt that would all happen in your fishtank though unless you left a window open and a heron flew in and you have freshwater snails.
