Hi, welcome to Reef Sanctuary!

I don't believe that the water movement is an issue. Most reef fish can handle a large amount of flow.

Three measurements that I don't see you mention are temperature, pH, and specific gravity. Daily swings in any of these (or in the case of specific gravity, rapid changes) can be very stressful to your tank inhabitants, and in some cases, cause death. Having a small tank like yours makes it difficult to keep these levels constant. Maybe you should test these two or three times a day, just to see how they're doing? Make a little chart so that you can keep track. Hope this helps!
