Mine's doing quite well, Quinn, but it's being a PITA to my pectinia where it's been sitting for the past couple of days. Moved it gently to another location yesterday, but it was back on the pectinia this morning

Gotta get my turkey baster out again and blow on it some more to get it to move. Better yet, baste the whole tank and it may take a road trip. As long as it doesn't find the powerhead it's fine
I attribute my success with this animal because I use Marine Cuisine to feed the fish in my 42 gal. I melt the food and mash it up pretty good so there are many tiny particles the feather star can filter feed from.
