I'll give the hybrids a pass, as just about every domestic animal has been hybridized ie breed, dogs, cats, rats, cows, horses, goats, chickens, pigeons so on a so forth. The tattoos though, I don't like them and I'll never buy a fish that has ugly blotches in the vauge shape of a heart, or flowers, or just the "blue" parrots that also look all blotchy and sick, and best case will lose the ugly blotches in a few months. I would support stores that felt the same way as me but every shop within an hour of me has tattooed mollies, BPs, and glass fish, and my biggest complaint is that it's poorly done (ugly/ dangerous for the fish/costs the same as the not ugly fish).
I tried to get into animal rights all hardcore in high school, I spent six months trying to free a monkey from a dentists office (because keeping monkeys is wrong), with pamphlets and wised up a bit, as of a few years ago the monkey is alive and well, and still in the dentist office.
And yeah, Wal-Mart sometimes has tattooed mollies.
