Nope. Roselines and cardinals are all fine.

Hmmm. Interesting. I know for sure ferts isn't an issue and from your story, hardness shouldn't be an issue either. So how do people do it? Unless the roselines are already picking the amanos off when they're only 2.5"? Their mouths don't seem big enough to pick at amanos yet.
Also, is there a point of not cleaning your sump that O2 exchange isn't as efficient anymore?
