I don't expect perfect husbandry in a pet store (would love to see it though!) They're only in a temporary home and are treated as such. I have a huge issue with misleading sales pitches though. I can imagine people thinking they're going to take them home, dump some kind of processed very much not alive food in the tank, never clean it, and expect them to thrive. If they do explain how to care for them properly, customers are going to see that the sign is a total lie.

Not to mention, the frogs in the tank the sign was on are a breeding trio and not for sale. Yet their tank didn't even come close to acceptable for long term care. You would think that if they're getting $$ from this trio, they'd actually put some thought and care into things before their breeding efforts fail.
