I've got a pair of clowns 8 days ago, no problems until today I woke up and noticed strange behaviour in the male (opening and closing mouth rapidly). I thought It was because yesterday I made a water change with vacuuming the sandbed, making the water go higher and creating less surface breakage. I moved my pump higher 1 an a half hour ago but to no avail. He didn't ate the first time, but after a bit he started chasing the food. Video:
What could it be?
Thanks
