In a perfect world everyone would do research before buying a pet. Or not be allowed to buy one unless they can provide the basic care for the pet to be happy.
People aren't aware of the responsabilities of a pet most of the time. Or they think they do. The sad thing is that having a pet is seen as having a new toy, at first its all exciting but then they just see it as a chore and just become lazy. Or they just buy it cause it's pretty, cheap and think it hardly needs care
In my opinion there is no such thing as a "easy pet" meaning a pet where you just don't have to do hardly anything and it will just mantain itself.
Every animal needs care, in their own manner, should it be a small fish to a big dog. Not only do they need their basic needs covered but they need attention and love too.
With those two things covered, it makes any pet owner a good one. But it doesn't mean I condone for the betta being in the bottle. It's very inconvinient as in it doesn't look like it's going to be cleaned much, water changes look near impossible to do there and it's much to cramped.
As a temporary home-- it's hardly passes as acceptable either. I'd say she should have put it perhaps not in a 10 gallon tank, but at least 1-2 gallons, which doesn't take much space and is more accesible to clean.
Of course the fish will not complain because it can't. I'm sure if it had a voice it would. The response and excuse of this girl isn't adequate.
All I hope for is that this won't become a trend, that we can somehow try to convince this girl about how betta's should be cared for and we somehow just keep trying to educate future and current betta owners about their care.
