How would tidal forces impact two habitable moons in a horseshoe orbit?
I saw this video a while ago, and recently it's gotten me thinking. Towards the end of Artifexian's video on gas giants and habitable moons, he mentions the idea of having 2 habitable moons in a horseshoe orbit. An example of a horseshoe orbit would be Saturn's moons Janus and Epimetheus. Once every 4 years, they swap orbital altitudes.
There's already been a question about seasons would work in this setup, so I'm going a different route.
What kind of tidal forces would 2 habitable moons in a horseshoe orbit exert on each other? Could it hinder the habitability of either moon?
When I say habitable, I just mean the usual stuff. Water, Breathable air, and somewhat Earth-like gravity. If it helps in forming answers, these parameters can be pushed. Never said humans had to live here.
I was imaging one moon as a mostly Earth-like planet, and the other as a mostly water world if that helps with answering this question.
