Found a few tiny critters in the back of my rocks. Can't tell if they're hydroids or aptasia. They are very small. Maybe 1cm max.

Waving around towards the center of the image.

look more like hydroids to me, the stalk is a bit harder and not like aiptasia body, but the left on elook more like aiptasia, can't confirm 100%
