Bettas are not supposed to be kept with guppies (although someone got it to work) as they resemble another of their kind, and so the betta will kill the guppy.I could be reading it wrong; I think I got KH and Gh mixed up, the gh is dark blue. But my test only goes up to 180. So, it could be higher. The damage is already done, I already have these fish so I might as well learn to care for them. I used to have my betta with them, are bettas and livebearers not supposed to be tried together?
I'll look into the salts. No other fish are in this tank besides the ones mentioned.
