I'm in favor of writing letters. I once emailed the people who make glofish at http://www.glofish.com/contact.asp and they were very responsive and even made changes to their website based on my suggestions. In their "care" section, they talked about water conditioners but not about cycling or new tank syndrome, and they didn't emphasize the need for a filter. After I emailed them about it, they changed the wording on their site and even provided a link to the nitrogen cycle page at fishlore.com.
The one thing they disagreed with me on was the need to tell people that glofish need to be kept in groups of at least 6 fish in a tank of at least 10 gallons. Here's a quote from their response to me:
"3. Stocking Density: Our research has shown that the stocking density for zebrafish can be relatively high compared to many other fish. For more information about this, please visit the following peer-reviewed research paper by the faculty at the Zebrafish International Research Center: http://www.nal.usda.gov/awic/pubs/Fishwelfare/Matthews.pdf. Specifically, page 4 notes that the, "Recommended density for growing juvenile fish and holding adults is five fish/liter [or 19 fish per gallon]." As this number is intended for researchers, it may not necessarily be appropriate for home aquarists. At the same time, it is consistent with our own significant experience with GloFish which have demonstrated that they can thrive at levels well in excess of 6 fish per gallon."
So, anyway, they may not object to the 1.7 gallon glofish tanks, based on what they say about stocking density. But it at least goes to show that companies do sometimes take consumer letters seriously.
