Off on a tangent here but what I dislike most are the LFS owners and sales persons who know better but will say anything to close a sale.
YES. And ignorant employees. Very frustrating.
What prompted me to make this thread was an experience I had this week at Petsmart. I wanted to get some ghost shrimp, but they said they hadn't got any in. I asked if they had any nerites, they said they were out. Then one said they weren't sure about the nerites because they couldn't tell them apart from the apple snails. Then the other said you could tell them apart by the point on their shells. I remember telling him that a few months ago.
To double check, I went over to the invert tank. On first glance I saw four baby (less than 1/2") ghost shrimp and probably five olive nerites.
Me: Hey, look you guys have baby shrimp!
Employee: Baby shrimp? We only carry ghost shrimp.
Me: Yeah, there are baby ghost shrimp.
Me: See, right on top of that group of snails. Look at 'em, they're so tiny!
Employee: Oh, yeah, now I see. I wonder how that happened. We haven't had shrimp in for weeks.
Me: Well, shrimp carry eggs, but the babies hatch into miniature adults. If you had a female with eggs and they hatched, as long as there weren't any fish in the tank, then they would survive.
Me: How much would four of them cost me?
Employee: *Points to price tag* They're 49 cents each.
Me: Full price, huh? Okay. (In the past this store has given away fry for free or a discount.)
After she netted out the shrimp, I pointed to the nerites.
Me: See those greenish snails there? And that one right there? I think those are nerites. *I point at the apple snails* See how these ones have stripes pointing towards the body? And these green ones only have streaks across the shell? I think that's another way you can tell them apart.
Employee: Oh. Well, to me, they're all just snails.
Me: Nerite snails are the best for eating algae. And they're great because they don't reproduce in freshwater so they won't take over your tank.
Employee: We haven't had an issue with the other snails breeding.
Me: Mystery snails lay their eggs above the waterline, so they're easy to control. But pond snails, ramshorns, and trumpet snails will completely overrun the tank.
Employee: Really? Wow.
Since this store has had a snail problem for years, I started to think she was just humoring me. So I wrapped it up and left. Afterwards I wondered if I sounded like a know-it-all. And thus, this thread.
