Pairing Question

[sanwixh]

I recently acquired 2 male P14's and in the process of saving up for a female P14 or Leo.

Question is will there be a problem with putting them in the same tank? Will the males have aggression toward each other once they mature?

Here's a picture of the two, both currently at 4 inches:

As rays mature some do get aggressive. My male p14 harassed my male marble terribly at times after the p14 matured and that was in a 750g. I believe it may be up o the individual rays.

Was there a female with them or is it just 2 males?

Will the aggression worsen if there was a female in the tank?
