New to the hobby.

My take on starfish is a "better left in the sea" approach as most ( but not all) don't survive in captivity to long, maybe 12-18 months at best. Anything that multiples fast I remove, as I don't want these things to use up valued space, but that's just my take. Some are predatory, some can pop a clam with easy, some annoy corals, and some do a great job of mixing sand....
 
Ok so here’s something else. I have had my tank up and running for about a week now. Ammonia had risen to .25 and nothing else. I’ve also added a raw shrimp in to the tank to start to help the cycle move a long a little faster. Should I do a water change now? Or wait for another week or two?

Patience grasshopper. Patience.

No water change until there is 0 ammonia and nitrite. By that point, you should have some nitrate so do a hefty (20-50% - depending on how high the nitrates are) water change.
