I don't think there is a list, but if you go to the species profiles, there is an "agression meter" at the top of each profile. You'll have to look up individual fish and find the ones that say peacefull community fish, or something to that effect. While youre there you can look at the other aspects of potential tankmates, eg water temp/quality, food, availability etc.
If you go to the species profile, down at the bottom of the screen in small print is a link to find suitable tankmates. I don't know how the list is compiled, but it is a good starting point. These claim to be common fish.
