Help with new nano.

[DocReefer]

New to nanos, I was wondering if anyone can help me with my green star polyp not extending fully . Other "animals" include 1 blue leg hermit, 1 candy cane coral, mushrooms and a torch coral.

3.5 gal nano. 5 lb LR for fitration and 18 W CF light. Water conditions are good. Water changes weekly. About a 5-month old setup with animals in the last 2 months.

Animals are fed about weekly with ComboVital (with shrimp pellets every so often for the hermit crab).

I was just wondering if the unextended green star is a sign of something bad to come.

Thanks for the input.
