They were actually more accurate then they usually are. And that's saying a lot for PETA. When they say 95% are caught wild they are refering to marine fish not bettas or all tropical fish. It is true that the majority of marine fish are caught wild.
And yes there are fish that use tools for catching prey or protection. Some fish have been observed using rocks to crack open shellfish.
I'm no fan of PETA but I don't see any information there that is so horrible. They encourage you to have the biggest tank you can, treat your tap water, test your aquarium water, have a filter and heater....that's not such a bad thing.
Am I missing something?
