Oh good lord, they are everywhere and in another of my tanks today as well - I'm conflicted, I'd love to take an algea brush to the glass but if they are eggs... well, I don't want to harm them - then again, I don't want 2 dozen baby snails either. Every once in a while, one will go free swimming, my clowns will eat it and then spit it out.
The picture I am attaching makes them look slightly bigger than they really are and the picture doesn't really show the quantity of them either. I just wanted to give a visual on what I'm talking about.
Hmmm, I just tried about 20 times to upload and it won't let me...
