hi does anyone know how to get rid of these i cant get a harlequin shrimp as got a linckia star that i dont want lose, but i am getting fed up of picking them of the glass everyday theres hundreds of them i dont overfeed the tank so dont know why they are multiplying so much as a last resort i suppose i could move the linckia to my other tank and get a harlequin but what do i do with it after it has eaten the asternia although it would probably die of old age before that happened
