I have been researching tribbles and the food combinations to make different types of tribbles. There are a few good sites that go into detail on how this is done but it didn't satisfy me. SO what I did is I took the info from the four best sties on tribble breeding and combined the stuff into a single spreadsheet.
I have the various tribbles in rank order and grouped by buff that they give. (description of buff is at the bottom of the chart) and this is cross indexed with the what they would produce given a specific type of food or drink.
This is a combination of may people's work and I provided links to the sources used at the bottom of the page. Take a look and let me know if this is useful.
