astrea snails/coralline..

[ChazYork]

my astrea snails are moving over the LR i have and i've noticed white streaks behind them and in the general area of them cleaning the LR - are they eating my coralline algae and the good stuff on my LR?

I think the only inver that can eat coralline are urchins. Snails are good thing they keep things clean. I wouldnt worry about them messing anything up on the rock.
