I don't think I need to just yet as I have more than enough algae for it to feed on but can anyone recommend something that I could supplement feed my blue linckia?
I had mine for over a year. It never once activly ate anything I tried to give it. In fact, it would move food out of its way.
I think they do best in a mature and somewhat dirty tank, algae wise and such.
I do not know of any supplemental food for Lynkia Starfish. They eat microscopic bio-film algae which really can only be produced in a mature aquarium.
