I've said this before, I'll say it again.
If you do not like *****, and many people like to complain, then DO NOT BUY ANYTHING FROM THEM - not cat food, not dog toys. NOTHING. I hear people complain, but they are shopping there? I know very little about what my ***** does because I purposely do not shop there unless it is an emergency. But if you buy anything, you support what they do with anything.
The damsel thing, BTW, is still a tried and true method to cycle a tank. And for a 20g, you would use somewhere between 4-6 damsels. I don't care for it, but it is a viable method.
Many local LFS have fish commonly treated with copper. That is quite customary. They just may not tell you. Damsels are commonly beaten up because they are naturally territorial, treated like feeder goldfish, and are of little value. But that is not unique to ***** for sure.
So my main complaint with ***** threads is that they are an easy target. The are accused of things that are common in LFS' around the country, but no one says a thing about them.
I do not think it is fair to call ***** employees such names. Many do care for what they do. Many are knowledgable people. Use your common sense for your *****...but if you don't like what you see, LEAVE THE STORE WITH EMPTY HANDS!
