I wonder what kept the asterina population in my big tank in check?
I figured I didn't have any but now that all livestock is out and most of the water is drained I am finding some asterinas and several babies!
How crazy is that?
The whole time the tank was up I never saw any!
They seem to big for the porcelain crabs since they are more into floating foods.
Hermit crabs? Do hermits eat asterinas?
Or my shortspine urchins?
