That is a flatworm in the picture.

First of all there hundreds of different kinds of flatworms and most are literally impossible identify. Most people have flat worms in their tank and don't know it. Most are harmless and don't multiply into plague proportions.. A few flatworms give the rest a bad name.

Allot are specific feeders and only feed on one thing and once that food is removed they die off.

I redid my post. I see that they are all over. I have known people to use flatworm exit before but be careful and be ready to do a large water change. Problem is flatworm doesn't work on all flatworms. I would remove a few and try flatworm exit on them before you treat your whole tank.. Flatworm exit also can kill some invertebrates in your tank and will have to be removed.

If these are just attacking one thing I would just remove it and dip and quarantine.

So Maybe I should not completely worry just yet? They are present on all of my corals, just that they seem to be more concentrated on the mushrooms. Now maybe that is just where they originally hitchhiked in on. I do want to say that thay mushroom has split twice since I put it into the tank. I started with one about 1.5" and now I have three that are 4-5" across. This happened in about 2 months.

This being said, I don't necessarily think that they are killing my mushrooms. It doesn't mean that they are not. None of the corals seem to be bothered.

You can see them on the fingers of my frog spawns and everything still fully extends as normal.

I am not really comfortable with doing FW dips with any of my corals.

Do you think that I should still do the treatment?

What bothers me is they are all over. Usually some will wander looking for another coral as a host. Most flatworms will stick to a certain host like just a goniopora corals, or just acropora corals or just mushroom corals etc. They might have just exploded and are just looking for more hosts and can die back if no host is found. Don't panic.
Usually once the host coral is gone they die. But sometime there are flatworms like the red variety which can exploded for what seems no reason and needed to be treated a different way.
When I say dip I mean using something like lugols or one of the coral disinfectants, not a freshwater dip even though that would likely work too just a little more harsh.

Oh. I have never heard of Lugols. If I can find some I might try that with the frog spawn(s) and the other corals that are not attached. The problem is that the ones that are attached to the rocks...I don't think I can dip those.

Perhaps just pull the rock with them attached and use a spray bottle to squirt the solution on them?

Also, what about the ones that are not an anything in paticular like the ones on my glass?...and I'm sure that there are some wandering around my rock work as well.

There are allot of different dips like coral r/x,.

I am not saying dip everything.. If these flatworms truly survive on mushrooms alone you dip the mushrooms and quarantine them till there are no more flatworms on them. The ones in the tank will starve to death without their host. It is possible that you have something different and they can survive on other corals though in which case you may have to figure out another way to get rid of them..

Here is a example. Acropora flatworms which used to be a big problem only survived on acropora. You remove the acropora from the tank the flatworms in the tank would starve and die eventually. You then treat the acropora in a quarantine tank that is easier to treat the acros in with out disturbing the other corals and invertebrates in the main tank.
