Furcata rainbowfish in 6 ph?

[oscarbuffalo]

I want to house a group of furcata rainbowfish with a a pair of german rams. German rams have a lower ph requirement and are very sensitive to the water, so i was wondering if furcata rainbowfish would be ok with 6 ph or if german rams are ok with 7 ph.

A ph of 7 is fine for both and actually both can acclimate to even higher ph. The reason I don't like to keep a ph of 6 (unless it's for specially fish or breeding) is because at a ph of 6 or lower biological activity stops and BB can begin to die off.
