I used to get tons of TetraMin stuff from my friend who worked for Pfizer. Every Xmas.Hawkeye said:This probably only interests me but...
Spectrum (aka Rayovac) really only recently came to become the owner of tetra. It was part of Warner Lambert's consumer division loooooooong ago before they were wholly acquired by Pfizer. Pfizer then spun off Tetra thru a LBO in 2003...then resold to Rayovac in 2005.
yes the makers of listerine and lubriderm actually also made tetra fish stuff at one point! I used to buy a lot of turtle and fish food for cheap...
