What the heck are these?

Just got back from a 3 day vacation and these things are all over my tank. My fish aren't looming so goo either. What are these and what do I do about them?

Can we get a clearer picture? Are they on the glass? How do they look - solid or cloudy? Do they sway in the current? Did you make sure your fish were cared for while you were away?

Are they alive?

No that's as clear as its going to get. They look like they're moving. They look like light brown sesame seeds. They look like they sway in the current. No I did not because I was only gone for 3 days I fed them just before I left and then when I came back. But I just woke up and now they're gone? I cannot see any of them. When I get back from school I was going to to do a really good gravel clean and water change.
