so I don't really need to worry about calcium in the water for the shrimps shell development? they get all they need from food? I think my brother runs his tank somewhere around 7.0 ph (could be wrong, I'll ask again tonight) is that good for most shrimp? temp about 78? I'm still unsure about what shrimp I want. I like the blue shrimp, but the one's above are nice too, anyone have any suggestions?. Do I need to pick a target group or can I just try to keep the one with the most needs happy and forget about the rest? will some fight? will they pair up (and maybe dance
) if I get the right ones?
Thanks for the help guys, as you can see I don't really know where I'm going with this.
