Cichlid fanatic;2003874; said:I have 3 discus from my LFS that came from a wholesale and they great! They dont have any problems and eat like pigs! Not to mention they are growing like weeds. I was talikng about not living in RODI water. I dont have a RODI unit and I cant afford one. I have a regular cleaning schedule and they are living in great conditions just not over the top.
Maybe I've just had extremely bad luck with LFS discus. I think any fish store that keeps their discus in standard tanks would be fine for what you're looking for, especially if they've been there a while.
