Brown spots on Frogspawn

[jamesamantha]

Hello,

Anyone have any ideas what this might be? I have started seeing brown spots on my frogspawn and hammers. I have watched and I don't see any movement from the spots. I did an iodine dip thinking it might be some type of flatworm but the spots don't fall off in the dip. They are not extending like they should be.

Some places it looks like spots and in others more like a rusty film.

Thanks

No crabs in my tank. I have a few colonies of this froggie spread around the tank. They all have it. And the hammers.

Only live stock are two perc clowns, astrea's, stometella's, and whatever worms live in the sand.

Had them in the tank for a couple of years.

Dunno, that's weird. Definitely not flatworms.... May be some kind of algae?
