Pescitarian or vegitarian?

I've been a pearian (vegetarian who eats fish) for the last two years because I was gullible and thought that they treat fish well and just not cows, chickens, or pigs. But I'm debating whether to be a true vegetarian or not. One of the reasons I became a pearian was because my mom had been one for two years (now four) and I was starting to learn more about animal cruelty. But, shes just in it for diet reasons (ex. losing weight) and I'm in it for ethical reasons. And everyone already gives me a hard time for being a pescitarian (friends and such). Can someone give me advice and some articles about 'fish' cruetly because maybe it'll give me some motive? THANKS! <3
