PETA does not want anyone to have any pets at all. If it were up to them, all domestic animals would be gone.
However, I do agree with not purchasing bettas from a pet store that does not care for them properly. One purchased just opens up room for another to be abused. The more that are sold, the more that are produced and forced to suffer. Either way, the same number (technically MORE) will be abused and possibly die. It really is heartbreaking, but the only way to stop the supply is to stop the demand.
All animals deserve respect, not just the cute and pretty ones.Without "bugs", we would lose about 1/3 of our food, be nose high in decay, and entire ecosystems (including everything that supports the popular animals!) would collapse.
