Flatworms?

[TreyC2010]

I noticed these guys tonight for the first time. I haven't really watched my sump at night for a couple weeks I guess. Are they good/bad? Should I get a fish to control them? I still have some room for some company in the tank.

EDIT: I see it. Yes, those are flatworms. I'm opening the pic in photoshop to see it a little closer.

I was hoping you'd see it

They are not the Convolutriloba sp or the waminoa sp, which give people the most problems. So, if they are not an issue, I wouldn't intervene. I wouldn't get a fish just for that purpose. I have flatworms in my tank and they are just a part of my little ecosystem.

Cool. Thank you very much

These are mine from a couple of weeks ago. Mine are a smaller variety, but their numbers are higher than yours. Just an Acoel.

That's awesome. Did you put them on a slide and do that? Probably a dumb question but seems interesting.

 

[Lionfish Lair]

Yes and then put my phone up to the eyepiece. Many of my fish shed, so I'm always checking them for parasites under the scope.

these guys must be multiplying fast. They cover the top of the refugium section.

I have more than that. In places of calmer water they tend to really gather at the water line and just below and also right above the substrate. They bother some people to see them and they want to get rid of them. @twilliard is the one to talk to, to discuss options.

I trust that you know it as well. I thought it was neat to look in there and see so many. It's like you say, they are gathering in the calm water.
