Thanks, all. Tap KH is 1, so that's probably it. Gonna grab some coral today. They're perking up after the water change, but still not eating.

My tank's pH crashed overnight from 6.8 to 5.2, and my Discus are stressed. Running a 75-gallon with sand substrate, planted, and a Fluval FX6. Did a 50% water change, but they're still hiding. Any quick fixes?

Re: Help Identify Discus.

Thanks for the help, really appreciate it.

Hi, I'm reaching out for some help - I just got two new discus and I'm having trouble figuring out what they are.
