Pearls personality as good as Motoros?

[Kolossus]

Pearls I find are more aggressive than marble I have seen 6 inch disk pearls bully adult p14 of 16 inch disk at feeding time

I find my pearl less aggressive than my marble.

My pearl is among the smallest of my rays but is the most aggressive. These variations in personality is exactly why I say it simply depends on the individual ray, and less the species.

My female is ~10" and very docile. I had to separate her bc my marble was being too aggressive with her. I agree is clearly depends on the ray.
