That is commitment. I have not yet figured out the proper predator response for these pests. Wrasses I love anyway. CBB are also good pest control. But I still have vermetids. At least they don't multiply like they once did. Also 25 bumblebees.Just had an outbreak in my 200 gal waterbox, added six line, melanarus wrasse , 100 bumble bees and copper band all at same time. Will see how it goes.
They drill into the shellI’ve always wondered how exactly the bumblebees get at the vermetids. It’s not like the bumblebees can break the shell and I imagine the vermetids would retract into their bases when they’re attacked. Sorry I know this is a bit of a sidetrack but…anyone know?
