Whose eating my starfish

[Rmoore7167]

You will have to pardon me, but im only 6 weeks into my 24gal nano...I love it! anyway, we loaded up aquarium with
1 sand sifting starfish
2 turbo snails
2 nassa snails
1 peppermint shrimp
2 emerald crabs
10 blue leg hermits

well they are all doin a heck of job on algae, and I just started feeding 1ml every 3-5 days of artipods. I originally thought I wouldnt have to feed animals at all. I thought that everything lived off of detrious (sp?) matter and algae etc. But apparently Im wrong? What should I do? IM afraid of getting nitrates etc out of balance with feeding?

any help would be appreciated

Why do you say something is eating your star? Does it look like it is falling apart?

Its best to not include a sand sifting star in your 24 gallon nano, I'd suggest taking it back to the pet store.
