high ph?

Cardinal tetras? in that high ph? according to my lfs they are very difficult to keep alive, he said they lose them all the time at the store.
I have high ph in my tank and have been trying to lower it. The platies and guppies (a cory too) seem to have done well despite it, and have even adjusted to the elevated ammonia level.

All of the cardinal tetras on the market are wild caught. That is why they are so delicate. I've had them in my water of ph 7.4 with no problems. However, only after some time of acclimating them, do they become quite hardy.

For shoaling fish, you can't beat bloodfin tetras. They are the tightest shoaling fish I know of, and will adapt to just about any water conditions - very hardy.
