Your tap water is likely hard. The hardness numbers (you can find this out from your water supply folks, probably have a website with data posted) will tell us if the p|h may or may not lower once the tank is established. This is useful to know. And it might mean more options for fish.

As for the fish, have a read through our fish profiles. The pH range for each species is included. Profiles are under the second tab from the left in the blue bar across the top of the page.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

a fairly simple way to bring down your pH a small amount is to add a piece of driftwood. i added one and it brought my pH down from 7.8 to 7.6. this method does not affect the water's buffering ability and thus does not lead to unstable pHs.

I don't want my water to be stained, so that's not really an option

if you soak the wood in a bucket for a while first (how long depends on the individual piece) it won't stain your water.

Also with my experience I have found that malaysian driftwood does not release a lot of tannins into my water. You can soak the wood in water to help remove the tannins. Also with the malaysian wood it will naturally sink in the tank, so no need of waiting for it to become waterlogged before it will stay put.
