Can fish interbreed like dogs? My SO and I have been talking about dogs lately so the mixed-breed thing has been a regular topic of conversation. Last night we were at a Thai restaurant with a large fish tank and some gigantic fish. Too big for the tank, in my opinion. And that got me to wondering....can different kinds of fish, genetically speaking, be bred with each other? Even if they wouldn't do it on their own (mating rituals, etc.), could they do it with a scientists help?
