If you have read some of my posts you will know that I have hard water that has a high pH(pH=7.8 ). It seems that a lot of fish don't like that, especially rams. I've had a really hard time trying to keep blue or gold rams and they never survive my QT tanks. I'm depressed about it because I like them alot. I did see some adult rams the other day in a pet store for $8.99 each and I asked the owber to test the water, she did and it was pH 7.8. I became encouraged by this but I can't bring myself to see any more of those fish die in my QT, so I haven't purchased them. I keep checking my N levels and they seem fine. My clown and Yo Yo loaches do well, as do my dwarf gouramis and black ruby barbs. I want another fish to put in my community that can tolerate hard, high pH water. I do not want to try to modify the water chemistry. So, if anyone knows of a good community fish, that is not a bottom dweller, that can tolerate hard water and high pH, I'd like to know.
