I purchased a package from a web site and have had relatively good luck. The only really negative thing is they sent me the wrong shipment the first time so I got some starfish that I don't think my tank was ready to handle. However, I had to introduce them to at least give them a chance. A couple are doing well. That being said, I really like my red legged and blue hermits. There are always some in view and they are very active. My snails do a good job with the algae too, although I have sadly lost a few (out of 25) in the first 2 weeks. Other than that, I got 3 emerald crabs (some people hate them) and a sally lightfoot which I love. My Coral Banded shrimp is quite small and I want to add a cleaner shrimp as well, but I don't want any fighting. I say go for it, buy a package for your tank size, you'll be surprised how much it helps in general housekeeping and how cool the inhabitants are.
