I work in a petstore and i have to agree, some of my coworkers no nothing about fish dispite working there for years. think of it this way, they would rather sell you a few clown loaches at 9.99 each for your 30 gal then a few tetras at 2-3$ each... ive seen it myself, but i gotta say, its not always easy to give accurate information all the time unless your the fish GOD and know everything about everything fish related. I TRY to learn about fish in my spare time, I read things here, ask questions and learn, but most people DONT. Honestly, i know squat about discus, we dont sell them, and if someone asked me how many i could stick in whatever sized tank, what kind of water it perfers etc. In that situation, its either tell them nothing, you dont know, or try to sound like you know something about fish, cause you work in a fish store. I usually tell them i have no clue, and about half the time they dont mind, but half the time they get mad at my not knowing about fish we dont even sell. With so many hours of this kind of environment, it gets very stressful, and sometimes you dont even know what your saying anymore( especailly if you work closing shift and theres only one person in your department for 6 hours...) Sorry if i offended anyone, but i really get sad when I hear people talk so bad about people in these stores, when alot of them are beginners and haven't learned or have never been told. Instead of laughing at them, why not try to help them a bit? Ive learned quite a bit from some the people who come in the store, Im not saying ignorance is bliss , but i gotta say, most of the bad advice is just ignorant and not ill intended.
