just wondering because ive never looked in to them, and RO water seems a real pain to get so can they have water from a tap? Im not getting any Discus but im thinking for the future, so i know if they would be an option or not.


Thread moved here so you'll get faster responses. In my experience, no, and I do not believe you want pure RO water for them either. What matters most however is acclimating them properly as they are very sensitive to sudden changes in water conditions. Once properly acclimated, I find them rather sturdy and exciting to have.
Good luck!
for domestics, absolutly not. for wilds, only if your tring to breed. I have 8 adult wilds in tap water.
