So I got this couple of blue rams (deemed to indeed be male and female by some kind board members here) but I have another question. I noticed some things about their behavior of which I have recorded some footage:
-The larger male seems to be chasing the female a lot
-They can both lose their color/black spots and change back to bright and saturated in the course of a few minutes
-The female sometimes rubs her belly through the sand (as can be seen in the end of the video)
-The female doesn't always swim away when being chased and sometimes seeks out/follows the male
So is this normal behavior or what? Are the bonding or fighting? And what's with the belly rubbing?
