This question already has an answer here:

In my world, I'm planning to add a second moon which would be positioned closely to the first.

I was wondering what effect would that have on the tides?

    $\begingroup$ Your second moon can’t be “positioned closely to the 1st”. It will have to have its own orbit, with a different orbital period, so it will sometimes be near the current Moon and sometimes on the opposite side of the Earth. $\endgroup$ – Mike Scott Oct 11 '18 at 20:22
  • $\begingroup$ @Mike Scott Provided they were different enough in mass, the small one could be at a relative lagrangian point I think, and thus have the same orbital path. But then it would be far I think and not much of a moon. $\endgroup$ – theREALyumdub Oct 11 '18 at 20:50

    $\begingroup$ This is a subset of the question linked to by @Renan, and the answer there (which is good) applies here as well. $\endgroup$ – Gene Oct 11 '18 at 23:33
