Nice! BTW, that is a thinbar dat, Datnioides undecimradiatus, not an Indo dat, D. microlepis. Tough bugger hanging out w/ the true BW fish at 1.010 SG!

I was looking for the a chart that shows the differences of these fish, do you know were one is? They got it in as a micro, but I wondered in the back of my head if that was right.

Also, could the fact that it was in brackish water make its bars disappear?
 
Mine colors up real nice in my brackish tank, but I am jealous that he took krill from you already. It took a month for me to see mine!

Levi, heres that chart your looking for http://www.fishyou.com/fish-tiger.php
I dont think the brackish water has anything to do with the stripes disappearing or reappearing. It happens to dats all the time depending on their mood. Thats one tough thinbar making that journey, these guys can be a little touchy and usually would just rather prefer to die.
 
It practically didn't have stripes in the brackish water, looked like a silver with no stripes. Colored up nicely once we dripped him into fresh.
 
That store had a lot of great fish, including the Dat (unfortunately kept in brackish water), a great clown pleco that I picked up too, and the huge loach I bought for Rallys tank.

How can you tell?
The three straight and thin body bars and two tail stripes are trademarks of a thinbar (D. undecimradiatus). Indo dats (D. microlepis) typically have three or four body bars (the last two of which are thick in three-barred individuals) and three tail stripes.

Rally, wholesale lists are usually pretty outdated and will likely call datnoids either silver (quadrifasciatus) or gold (microlepis). The reason for this is that thinbars and widebars weren't described as a separate species from D. microlepis until 1994 and 1998, respectively. Thus, with the exception of NGTs which were very rare in the hobby until recently, the industry only recognized two datnoid species until very recently.
 
He looks much better now, begging at the front of the tank.
