For a while now I've noticed my angels lying on the bottom of the tank, almost bending slightly.. Was wondering if anyone could maybe tell me why they do this/if it's bad, etc. (was like they were sleeping, but happens all through the day, and they do get plenty of "night time" for sleeping!)
And also a lot of the time they will sit at the bottom of the tank, but upright.
Just asking because I've never seen angels do this in any aquariums I've seen
