No, Do not trim off dorsal.
Is nice looking hi-fin red velvet swordtail that thrive in hard ,cool,alkaline pH 7.5 to 8.2 water and enjoy water movement.
Ammonia and nitrites must be ZERO and nitrAtes under 40ppm
P.S. swordtail's can move forwards or backwards faster than you can blink when the want/need to.
