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.
