Hello!
So after a very long time searching on my water supplier’s website, I finally found the Gh of my water. And no, it was not located in the article about aquarium fish and cycling, where it should have been. Anyway, my Gh is about 80 ppm. What sort of fish can live in that?
Thanks.

Angelfish, most tetras, barbs, Bettas, gouramis, rasbora, Corydoras and small species of suckermouth catfish all occur in soft water (GH below 150ppm) and a pH below 7.0.

Livebearers (guppies, platies, swordtails, mollies), rainbowfish and goldfish occur in medium hard water with a GH around 200-250ppm and a pH above 7.0.

If you have very hard water (GH above 300ppm) then look at African Rift Lake cichlids, or use distilled or reverse osmosis water to reduce the GH and keep fishes from softer water.

Lots of options in fish, as Colin said. A GH of 80 ppm [= 4 dH] is soft.
