Ok, so first one is either jaguar ray or orbignyi, mostly likely
and second one is yepezi.
which one is more "desirable" and how long would each last (avg growth) in a 6x1.5, 7x2, 8x2.5? also, which is the easiest to care for? If I know right, a jaguar ray will get too big for what I want. I am planing on at least 10x4x3 eventually, but IDK when, so something that will fit in an 8x2.5 for a few years at least would be cool.
