If you're positing a planet with more than one moon and don't want tidal
effects to be disastrous, the main criterion is mass,
bearing in mind Newton's gravitation equation. All the examples we have of
multiple, high-mass moon systems revolve around
vastly more massive gas giants where your damgerously-high-tide effects
don't matter. Mars has two moons but they're both tiny
and would have a negligible effect on any Martian ur-water/life.
You may also want to consider the fact that on a planet with a massive
multi-moon system (because of the effects you describe)
landbased life may simply not have been able to evolve in the first place -
I don't know, I'm an astronomer rather than a biologist!
