where can i go to read a good article on a beginner's guide to keeping stingrays? I'm near L.a. ,Cal. When i was in san Diego, I saw some very small ones swimming in a channel when the tide was going high.I don't want to get one if it's quite a hassle to keep. Does anyone know what kind reside in San Diego? They did have spots on the top and are light brown .Anywhere i can go to read on this?
