I was acclimating a blue tang today. I turned my lights off for a few hours and when I flicked them back on I saw a colony of these little red worms slowly moving around my rocks and glass. There must be hundreds of them. I’ve never seen them before. My tank has been up and running for almost 2 years. Im currently running out to buy a6 stripped wrasse to help clean these worms up but what is it and can it be harmful to my tank. Thanks in advanced!
