You are adding way to much too fast. I know from experience that I just went wild and added a lot of stuff with my new tank. My LFS said it was okay, but the people on here said it wasn't. Well, I went ahead and ended up getting myself in a big mess. Lets just say there were a lot of deaths and stress on me. (Like making a 15 gallon water change in the middle of the night!) Now, I am scared to buy anything else for my tank. Just wait a few weeks, the longer the better. Please.
Sorry if I sound mean or anything, but...

(Another mistake I made was that I didn't know that the choc. chip star was a carnivore. I'm sure you already know that, though.
