Hello, I was wondering if anyone knows the technical definitions of Half moons, half thumb dorsals, high/super high dorsals?
I have a trio of Moscow Blue HTD's, and a trio of Platinum Red Mosaic half moons, but I'd like to know exactly what specifications are required to give them those titles.. For example, how long does a dorsal fin have to be (in ratio to the body) to be classed as HTD?
I know with Betta a half moon has to have the 180 degree tail, and I believe the edge has to be straight, but it doesn't appear that guppies require the straight edges to be classed as half moon.
