Mushroom Question

[Noober]

Sometimes my mushrooms curl on the edges, sometimes they dont. My water paramaters seem to be ok. Is this normal for them to do this. I've seen several tanks that they look perfectly round. Anyone have any thoughts on the subject? Thanks!

Mine change sizes and shapes throughout the day.

Often the edges will curl either when they're irritated by something (like getting barnstormed by a fish) or when they've caught something small drifting by. I wouldn't worry unless it stays that way for a couple of days.
