hi guys,


any idea what these could be?

we’ve recently seen some squiggly lines of eggs but i’m not sure if they are related

Looks like flatworm shaped

flatworms, hard to tell…
but they look like harmless ghost flats

Definitely flatworms, probably harmless although they can quickly reproduce in plague proportions. I finally got my tank rid of them by adding a pair of Blue Star Leopard wrasses. They took care of every last one in short order. As a added bonus, they are model reef citizens, absolutely stunning to look at, and they're always out and about looking for more things to munch on!
