Can anyone ID this?

Can anyone iD what this is in my sump? It’s just started the past 2 weeks.

Looks like planarian flatworms. Try to manually remove as many as you can. Chemical eradication is possible but complicated because they can wipe your entire tank if enough die at one time.

They aren’t going to eat coral or anything but they will reproduce like crazy in an aquarium and eventually grow on top of everything...

Where do they come from? I haven’t added anything in several months.

The eggs are really small and it's hard to say how long it takes for them to hatch.

I rubbed my finger across them and it looked almost like wet rust and they disappeared.

yup flatworm...just went through it....looks like reef flakes stuck on stuff.

Ditto, flatworms. I have a small number in my fuge. Haven’t seen one in the display. I do have a sixline Wrasse in there so I would believe he is controlling any of them that make it to the display. However, those that are in my fuge are bothering anything so I don’t bother with the tedious task of sucking them out or throwing chemicals in the tank.

Great looking fuge btw.

Those populations will flare up when there's a lot of detritus and food are available. More filter sock changes mad and maybe something cool to put in the fuge to eat the extra food and the maybe the flat worms.

Yes it’s been 2 weeks since I done my last water change today so detritus was getting piled up. Thanks y’all!

I put a springer damsel in the DT and he ate whatever I had left after Flatworm exit.
