Endler Livebearer in PH of 6.6

Hello, I've had my first endlers for about a month now. They're in a 20 gallon tank with a betta splenden, blue velvet shrimp, and red crystal shrimp. I have 12 male endlers.
My ph is 6.6, I've heard lower ph on hardwater fish can cause organ failure and shorten their lifespan, is this going to happen to my endlers?
When I got the red crystal shrimp I didn't realize they were so drastically different from neos, and I worry raising the ph will kill it. I've also read numerous sources saying 6.4-8.0 for endlers works fine but I've also had people tell me it's not safe, am I over worrying?
What I mostly want to know is if the 6.6 ph is making my endlers suffer or if its actually okay for them but not ideal. Thank you for the help!

 

Hardness and ph are different things. Ph is alkaline or acid. Gh, kh is your hardness.

Oh alright I see, I'm getting a gh/kh kit tomorrow, what should I look for involving the endlers hardness? Is a hard gh/kh possible with a low ph? How can I increase those?

 

This should help you understand it alittle better.

Thanks!

 

They'll do fine at an pH of 6.6. I'm saying this from experience. Most people who say differently, just work with the copied text that all livebearers need hard water (which isn't true by the way for it goes for a large number of livebearer species but for sure not for all). If someone is saying the opposite (so, claiming that it goes for all livebearers) is lacking knowledge. PH is of course not the hardness but does associate with a higher or lower hardness.

I tested my hardness today, I have 3 for GH and 2 for KH, I'm assuming this is pretty low for endlers, how can I raise it?
