I don't work at an lfs,however I couldn't help hearing a conversation between an employee and some guy.Of course the lfs carry's blacktips(only two).So the guy points he wants one out.The employee goes into the backroom to get something.He comes out with a large styrofoam transporting box,which is lined by a plastic layer in which tankwater is poured into.So the employee has somethings that looks like a fishing net,so before he is about to net one,he asks how large of a tank the guy has. Apparetly he was planning on putting it in his "big" 30 galThe employee says it won't work.So the guy says ok and goes to point at the guinea fowl puffer,the employee says no.The guy then just gets pissed and walks away.
