Cardinal/Neon Help

[discusguy]

Hi everyone, I'm new to this website and I just wanted to say hi first. But anyway, to the question.... This is kinda embarassing because I'm a discus keeper, but I cannot keep cardinals or neons alive for more than a week. I have hard water here, KH=125ppm, GH=off the chart, too high for kit, pH=7.6-7.8. I get my discus from a local breeder who has the same water as me, henceforth the discus living. I really like cardinals and neons, but I can't keep them. I actually read on this forum of some people who have cardinals and neons at high pHs like mine. Any help anybody?
Thanks,
-Nico

Are you sure your discus aren't eating them? They have been known to eat any fish small enough to fit in their mouth.

Don't get me wrong some Discus don't touch fry. A friend of mine had his with some endler's for months, until one day he didn't feed them and all his little fish were in pieces.

No, they're not even in the same tank, my discus are in my 60 gal. BB tank. I've always tried neons and cardinals in my 31 gal.

Well in that case. Look at useing CO2 or peat moss in your filtration.

With your nice high KH you have a lot of buffer room for your ph to play with. Otherwise, get some nice fancy guppies or African Cichlids.
