Oh yeah, know the common diseases to help you pick a healthier fish:
little white dots (on fins or all over the body) = ich (easily treated)
red outlining the ends of light colored fins or very dark, unshiny tips on fins = fin rot (easily treated also)
Read up on the other diseases, but these two are the first thing I look for as they are very common in petstore shopping!
