Thanks for the responses regarding diet requirements.
To further probe about the problems with a rosy-only diet... are there other fish that are considered 'better' nutritionally? I am going to attempt to introduce worms as a suppliment.. but my question is how much and how often?
So, just to recap my "one more" question, which apparently is two 
1. Are there other fish that are better than Rosy's to feed?
2. Worms - how many? how often?
Thanks in advance!
