I found this guy in my filter sock. He got as small at 2 inches then stretched himself as long as 4 inches. Is this some nice happy work that will eat the waste in my tank or something I should throw in the trash.
If there is one, then there are many more. So one not going back in wouldn't make any difference.
It's said that they multiple because of available food, so if you see a ton of them, then you may need to vacuum the substrate a little more.
I have a bare bottom right now. This is the first time I've seen one of there guys. About a year ago, I thought I saw something in the rocks after the lights went out that didn't look familiar but I wasn't able to get a good look at it. By the time I got a flashlight out it was gone.
