Started with all new dry rock and dry sand. Cycled tank for three weeks then added a pair of clowns, a peppermint shrimp and 6 snails from LFS. Tank has been up for 6 weeks now.
tonight while doing some maintenance, I shut off all pumps and power heads. After a few minutes I noticed the glass on my tank was now covered with tiny white bugs moving about. I had never seen them before. But now hundreds covered my glass. I took a few pics and then turned my pumps back on. Many disappeared, but many are still clinging to the class and still moving about after a half hour or so.
Are these pods? Or something bad? Pics attached. Sorry, but my camera could not focus on them any better.
