I want to express my gratitude. Having tried most methods of Aptasia control (to no avail) the Berghia you have supplied are a god send. Though not immediate, the Berghia love to hunt, snack and wipe out the pesty, nuisance Aptasia.
No chemicals, no...
I got them this morning at 11 and acclamated them for 2 hours before putting them into my tank. I just checked on them and saw one eating an aiptasia. They seem to be doing fine. I'll keep you posted as their progress continues. Thanks again!
