Discus breeding tank size matters

[Liber]

I wanted to get some thoughts on discus breeding tank size matters. My setup has been stable, but I am trying to avoid guessing before I make changes. What would you check first?

I would start with the basics and write down the recent changes. Tank size, water changes, feeding, and stocking all matter here.

That sounds familiar. I had better results after slowing down and changing one thing at a time instead of chasing every possible cause.
