I got a group of 3 platys. One is very young (about an inch long) while the other two are bigger (about 2 inches long). Out of the bigger two, one is constantly following the other one (and never the other way round) and at very close proximity.
The question that I have is : is the chaser a male who is just always trying to mate with the other one who is female? Or is this just normal schooling behavior where they just go in the same direction?
To me they both seem to be male based on the underside backside fin which is thin and long on them both. But the way one is always following the other (and never the other way round) and at so close proximity, it is giving me concern that it may be stressing the other one out. Should I be concerned or is this just normal schooling behavior?
