Question
I have these things stuck to the glass in my tank there tiny have to look with a magnifying glass they are translucent and look almost look like a half of a clam is stuck to the glass I also have black fur with bubbles in it almost look like eggs please help

Answer
The stuff on the glass just sounds like slime that may occasionally show up, will wipe off easily. The black fur with bubbles, sound like they most likely are eggs. Watch the eggs, most likely will can confirm they are eggs if a pair of or a single fish watches over them or fans them with their fins. Most often the parents do not go to far away.
