yep, that goes for all fish really. it makes me angry when ppl ask what sort of condition should i be keeping my fish at, u think they would find out how to care for them first before buying a living animal.
i dont think its really up to us but more for the ppl that are buying and selling these fish.
not at all, in fact i would be against them. its one thing to have them as ornamental its another if they breed.
not really, they're a lot more unethical things to worry about then GE fish.
if their not infertile i would suggest not to have them for sale permanently.
