i was just cleaning out my tank and i found little black hard bubble looking things in my tank.First i thought it was alge but i scraped one off the rock and it's round and it feels like something is in there.help pleaseeeeeeeeeee.
Sounds like bubble algea. I would remove it as most people think of it as a "bad" algea...

p.s. If you pop it, it will release spores and grow many more if a preditor is not present in your tank.
