Can fish live in water that has a pH of 8.4?

can fish live in water that has a pH of 8.4?

 

Not sure of too many fresh water fish that like the ph that high, but there are quite a few salt water fish that do. ie. Lionfish and Moorish Idols.

 

Of the freshwater fish that I know, certain Cichlids like hard water, and pH of 8.4 would probably be OK for them.

 

Very few will really tolerate that. However,African Rift Lake fish love it. So really any fish from lake MalawI or lake Tanganyika, like Synondontis Catfish or African Cichlids.

 

My tank has a pH of about 8.2 or 8.0 usually. I have swordtails, guppies, cories... I don't know why my pH is that high but my fish are fine with it so I don't add any pH down or anything like that.
