I like it if the person at the fishstore knows what they're talking about though

Then again, there are plenty of customers out there who think they're right, even if they're not... and there's plenty of people who don't listen anyway, even if they're paying for the advice (e.g., at a vet clinic...)...
A couple weeks ago, I went in to the local chainstore (the guy who runs the little fish shop I usually go to apparently retired

) to replenish my neon school (attrition over the course of almost a year had left me with three), and the guy in the fish department told me to wait, since this shipment was apparently not doing too well, though they looked ok. Went in a few days ago, apparently this batch was doing better (and so far, all five have been doing well

). He wanted to know how big my tank was, how long it'd been running, and what other fish I had... While I was there, a couple was looking at fish, trying to decide among the several "five for $5" fish there. They decided on serpaes, and the guy asked them how big their tank was... "oh, a couple fish bowls, we want more fish for our money! It'd be cool to have one in each around the house!" "uhhhhh... these are schooling fish, they need a bigger tank..." "so what can we put in a regular old fish bowl?" and he stood there for a couple minutes obviously trying to decide wither to tell them anything, but eventually decided to sell them a betta instead (more expensive per fish, but more likely to survive under those conditions...). The look on his face though... I think what he was thinking was "no fish should have to live in a fishbowl..."
