I have mine linkia blue star fish since i have started my saltwater aquarium before 1 year.
I have a lot of experience with them, so if you need to know something about them just ask.
I didn't turn on skimmer in first 8 moths, i have put at least 30kg of live rock.
In cooperation and great help from Mr.Schumaher Claude ,Fauna Marin company I have started to dosing Ultra Bio, Ultra Bak and Ultra Min - s.
Parameteres must be stable with no temp,spec.gravity and pH shifting.
I have tried many types of foods to feed her and only one combination was good for her,she has started to eat. My starfish gone through many difficult times, I had some problems with her tissue which is going to brake up. She has survived and still my favorite animal. If you want pictures I can post them.
Best regards,
