Mudskippers

Colony of Periophthalamus gracilis (Slender mudskippers) in my tidal aquarium. Time-lapse photography condenses 4 hours into 3 minutes. A complete “high tide” phase is shown in this video

so great! If you don't mind me asking, so roughly how active are they in the water when the "tide" is in? Do they generally just use that time to stay above water?

There not good swimmers so yes on top when the tide is in
