I think its digusting how pet shops can keep these clean enclosures for birds, rodents and dogs etc but have no idea how to look after fish. I think fish are often mistreated because they are difficult to relate to. as they are in no way anything like humans. Ie the SPCA can take away your dog if you keep in chained all the time put no one will even turn a blind eye if you keep a fish in a tank far to small for it.
As for the quality of goldfish, I dont think goldfish are a very good fish for beginners, they have a huge bioload ,they get huge, they are not a natural animal and for some reason people think they can be kept in small prisons known as 'goldfish bowls' :evil: .
In england I think the chain petshops there all have policys to not sell bettas or goldfish in bowls and advice people about the correct filtartion and tank sizes. I think someone should petition to have something like that happen here.
