Either tonight or tomorrow night i'll be ordering some C. Sajica's of aquabid.com. THe owner is not yet able to sex them, so i'll be ordering about 4 of them. My only question is how so the tank be set up for them? Should I start adding in rocks and slate and see if they start to pair off? I'll be housing them in a 30gal for now, and them move one pair into either the 55gal or 75gal. Thanks
