I would have heartily laughed at every stupid thing that he said.I did not like Beital's. The guy who runs the store gave me a speech about what I could and could not do with my tank and:
a) told me plants cannot go into an uncycled tank, and do not reduce nitrate
b) told me I could keep red pike cichlids in a 55. When I told him they wouldn't even be able to turn around, he told to get a bigger tank then, even though I told him the tank was in the wall, and I had no intention of ripping the wall apart again to put in a bigger one, and wanted a fish that could live out its life in a 55.
