Perfectly normal. I love it when mine does that! My Senegal and delhezi do it as well. No clue why but some days they'll just chill and other days they'll be all over the place

I imagine it has something to do with getting air from surface after meal

i'd say maybe they have poor eyesight so they use the glass as like some sort of "guide"? or either that they are just restless:D
