However Ive seen pix and have read that some of you have them in your reef tanks. I would love to have a puffer and would love to know how all of you feel about puffers in the reef...

    I tend to subscribe to the idea that a new tank should cultivate hitchhikers and let the system reach some equilibrium BEFORE adding fish. Reef Keeping magazine had a fun article on live rock hitchhikers that references this great post by Eric Borneman on the subject...

    I want to add a few sea urchins in my tank, but, everything I read says that they may mow down my polyps. Can I get some advice from someone? Any urchins in particula peopl ehave in there tanks that don't kill corals?

    I cant remember....but I think I read somewhere that coraline grows faster on a newer live-rock that you add to your tank IF IT IS TOUCHING an older rock that has a ton of coraline already on it.... (if NOT touching, it takes the newer rock longer to grow new coraline) Is this true????

    I have maintained a soft coral and fish tank for about three years, with no problems. Just recently, large amounts of what appears to be salt, have somehow found there way to various parts outside the tank and to the outside tank glass. I was wondering if anyone has experienced this or might...
