You still have a solar tide. That's about 1/3 the lunar one here on Earth. For the moons, it's likely totally negligible. Not only are they small, but most of the effect of tides here on Earth are a result of oscillations *pumped* by the tidal forces, not directly responding to them at that moment. But these things are so close in the speed the input changes faster than anything it was driving can propagate across any particular tide basin - the speed of sound in water isn't high enough to outrace the moving moon...
