Hey y’all, I posted on the first worm I found like a week or two ago and only got one response. But I just for another one and he’s a little darker than my first photos so maybe it tells y’all something different. He’s so small I found the sweet spot where my phone would focus. I haven’t put anything new in the tank for maybe 4 months or so. What do y’all think and should I be worried? I found this guy in my filter floss. The last two are from the one I found a week or two ago in the sand someone told me it was a bristle worm and not a problem. Is this second one the same kinda deal?
