I have a stirring pipe in my fuge. I went to stir my Chaeto and found these buggers climbing around the pipe. Do these look like Copepods or Isopods? If so, from what family?

Ugh... I thought the same when I first seen them. I hope not. I was looking at critter ID and I did see some Copepods and Isopods that were flat with tails like that so I was hoping it wasnt flat worms. See movie below. It was hard to focus but there are a couple shots of them.

They do look like acoel flatworms. Being as they are on the pipe and it is nice and clean. Hopefully it is the algae eating variants. I have them in my sump, but not to many as there is a corris wrasse down there at the moment. So far they have not hurt anything and are not seen in the display, as it is full of wrasses and things that eat them.

Agreed they do look like flatworms. Flatworms are not all bad and some are good so do not panic and most usually end up disappearing after a while.
Bad flatworms usually come in on a host. Some come in and they are specialty feeders like most nudibranchs and die off.
I had a bunch in one of my tanks in the basement I use to quarantine stuff and there were pretty many on the glass and now I can not find any.
 

Any special reefing plans for this week?
