Asterina stars all gone??

[Proteus]

The tiny white snails are collinista snails. Harmless. I have 540000 right now. I attribute it to over feeding as I picked up some anthias that were a little skinny. I've paid off the food and asterias ate on the decline but not so much for the snails. Funny though I don't have high nutrients. But the food is red plankton and cycopeze so I imagine it gets trapped in rock work
