For a while now I blamed my massive Coralline loss on my rocks on my tank switch but finally now that I decided to give it some serious thought I'm leaning more towards Asterina Stars, these guys have multiplied en masse (as they naturally should) and I believe they've eaten all the Coralline algae. I know Harlequin Shrimp eat them but I'm not a huge fan of adding livestock which I can't sustain and I really don't want to chop up chocolate stars to feed shrimp either. I've read also that Bumblebee Shrimp AKA Striped Harlequin Shrimp will also eat them but they are not obligate feeders like Harlequins therefore they will survive in the tank without stars. Okey, but I have concerns; Will Harlequins eat my Serpent star & the many Brittle Stars throughout the rocks Will my existing Peppermint Shrimp or Flameback Angel try to kill the little Bumblebee Shrimp? 1" max Will any future addition devour Bumblebee Shrimp Asterinas are also clean up crew, do I want to lose them to gain Coralline? So I'm not sure what to do, is there a member who's a harlequin owner who's willing to lend me a shrimp haha! or just stop thinking about it and be happy my Asterinas don't eat corals & let them be? I value the input I usually get from you guys so I'm open to suggestions. I guess it's my indecisiveness that led me to maybe have you help me decide.
