I'm pretty sure Justin is well aware of this. It is just a way for him to
have a larger, more spectacular disply of them, while they last. It also
lets him sell into the local market, easier. The impulse buyer rarely has a
brackish species tank ready to go. I'm sure he advises any customers that
don't know, to add salt for long-yerm maintenance or breeding.

Probably the same thinking as Justin. I was just surprised that they would
tolerate it and still look so nice.

Thanks Bruce,
