This may have been asked a million times before, but what parameters are best for a tank that woul house rams? I mean if one were to start up a new tank what size would be best for say 6 rams or so and maybe a school of tetras of some sort. What water paramaters are best for rams? Substrate and decor? I would like to start a tank someday for these as I thnk they are absolutely some of the coolest looking and acting fish I have seen.
