Is that normal?

My frogspawn and hammer shrink mid day. And literally expand the most in the morning. Im not sure if thats normal or something to worry about? My coral been there for over 2 months so they already acclimated to light. Its a frogspawn, and a hammer that do that.

Maybe, depends on some other factors but my hammers and frogs would come out after the lights ramp up and after the temps increase slightly. They typically begin to close up with the light cycle, although I am sure the clowns bashing them for cover at times probably helped promote stimuli

Any fish or shrimp bothering them? How long have they been doing this and any changes to the tank at that time?
