I just started up a new frag tank with a handful of frags. Upon closer inspection, what I thought was just routine new-tank algae has turned out to be a whole bunch of really tiny (possibly planaria-like?) creatures.



Each one of those isolated rust-coloured dots on the egg-crate is alive and crawls around. From what I gather, they're not the usual red bugs that people get because those are much bigger. Does anyone have an idea of what these could be?

I think they came in on a zoanthid frag, if that helps at all.

There probably just Flatworms. The link below might help.

I would go with flatworms as well. They can quickly become a problem if left unchecked. A pair of Blue Star Leopard wrasses did the trick for me in my DT. They laughed at double strength FWE.

If you have just a few, manual removal might work. Get a short length of rigid airline tubing, put a very short pice of silicone tubing on one end and a very long piece on the other. Start a siphon in the tubing and have it empty into a filter sock. Use that to suck them out. If there's more than a few, however, that'll get old real quick.

just keep a wrasse in every tank you have and flatworms wont be a problem. i normally keep a 6 line in my frags, i get them for free when people put that little cute active fish in a 20 gallon nano only to find out its eddie Haskell from leave it to beaver

Just to clarify, these things are like half the size of a copepod and they're basically covering every surface in the tank. Do you think a wrasse would actually even see them/be able to eat them if they're that small and so numerous?

Otherwise I might just dip the frags, sterilize the tank, and start again (I only have 5 frags in a 5.5gal so it's not like it would be particularly hard to do)

Actually, they all seem to be congregating around the light. I have like one "spotlight" on the frags,which are more to one side of the tank, and there's no flatworms on the other side where the light isn't focused.
