Finally they give up and the spots dissapear.

I guess it's a matter of time for them to accept there is no host in the
tank, but it certainly help to have at least 2 to keep company.

BTW, I add the second one months after, just make sure it's either smaller
or larger to avoid fighting.

If the smaller one you have is a smaller size female, and you add a
larger one which is almost certainly going to be female, you may get to
see a nasty fight.

Best bet is always add small ones.
