I'm a pescetarian too, and have been since I was seventeen. I have recently stopped eating octopus and squid as well as things I share air with. There are a lot of reasons to reduce or eliminate meat consumption, not just ethical concerns about animal consciousness - as long as you can enjoy a good quality of life and level of health without eating animals, it's easy to find adequate reason not to. (It's more efficient, more environmentally sound, less expensive, healthier, and, yes, provides a nice ethical nervousness buffer zone to make sure you're in the clear as far as the moral significance of animals is concerned.)
