Well the top ones look like the harmless kind, not sure about the yellowish ones. I thought they were mostly coral eaters.

Top ones are good, supposeldy, I'd be worried about the yellow ones though, sadly I don't think you can eradicate one without the other.

As for are they harmful to your seahorse, most likely not, but I'd watch otu for your corals.

I also have brownish flatworms in my aquarium and have had them for more than a year with out them hearting any corals. They seems to stick to the glass and especially where there are algae so I guess they eat algae of the glass?
My clowns love them and often pick them of the glass, so I see them as beneficial at least until now

As I have understood it is the red ones that can do damage to your corals by sticking to them and thereby preventing the corals from getting enough light?

well so far i have only seen them in my seahorse tank. but my seahorse tank is connected to my 75gal main tank. so its only a matter of time before they end up in there. how do i get rid of them? I don't want them eating my corals. where the heck did they come from? They just kinda appeared one day and are multiplying like mad.

Flatworm Exit is pretty good at getting rid of them. It is supposed to be reef safe, but I would sure check and do some research before I put it in a seahorse tank just because they are supposed to be more sensitive to stuff than other critters. The biggest thing to make sure you do with Flatworm Exit is to siphon the dead flatworms out once you treat the tank. The mass death of flatworms that the treatment causes can do damage to your system if you leave them all in the tank to decay...

I would just control them with regular siphoning. FWE is too risky IMO. I've used it in the past and the flatworms just come back. Not sure if its the FWE or the toxins from the flatworms, but great harm can be done to other inverts and fish in the same tank when treating with FWE.
