I have never really had an issue with pests in my Reef Aquariums over the years but eventually, it was bound to happen. I have Aiptasia now spreading throughout the tank, and a huge outbreak of Asterina Starfish, I'm sure they all slipped in somehow with frags E.T.C. Needless to say, I have tried all the usual to get rid of both pests, manual removal of the star fish taking out a couple hundred at time and they come back 10 fold. Aiptasia I have tried Aiptasia X, Joes Juice, Lemon Juice nothing seems to work they keep coming back. So now I am thinking of buying some animals to combat the issues, Harlequin Shrimp for the Star fish issue, and either a Copper Band or some Peppermint Shrimp for the Aiptasia issue. Before I jump in head first I would appreciate any feedback pros cons E.T.C to the above issue. Thank you!
