a species tank suites tiger barbs best

I really like the look of the rainbows but my Ph is 7.5 seems they like it a bit more acid, any thoughts anyone?
I diasagree with not keeping the tiger barbs. If kept in a large enough group such as 6+ then you should be fine. But as said pentazona barbs are also good.
Yes as above they aren't the hardiest fish make sure your tank is at least 4 months old before you add any. As with the tiger barbs the larger the group the better because the agression gets spread out in between the group therefore they shouldn't be as nippy. And a bigger shoal looks nicer too.i keep 3 pentazona barb used to have 6 but finrot killed them before it killed the neon tetras
imo there a pretty fish but a pretty weak fish
