When your setting up a reef tank is it good to get a package that come with snails star fish ect bc there's some websites that offer a lot like lobster shrimp crabs ect in a package are those worth getting
Sometimes they are if you know what to look for in the package. Getting one too large could be a problem, and also stay away from the sandsifter starfish.
I personally prefer to add CUC gradually as I see the need for more.
The packages from reefcleaners.org are great. Packages are a great deal price wise, but you run the risk of adding too many cleaners at one time, then having half of them starve to death.
