Anyone keep Bucktooth Tetras?

[JRT83]

Just set up my 55 gallon tank that had been sitting empty for over a year and decided to try something different besides large CA cichlids so grabbed 12 Exodon Paradoxus. Have any of u kept them before? If so, any advice or info that would be helpful? I've researched them quite a bit online but would like to hear what has worked for other people. I got 12 that range from 1-1.5 inches, here's how I have set it up to start...

you can probably put in double the amount that you have right now because they like their tank to be a bit overstocked. It reduces agression within the pack.
