Hey man very interesting conversation. I've known many of people to have failed with this fish, and others just got lucky with one that was already eating brine at the store. Unfortunately the person selling it to you might not know or care to warn you of its proper care. But I can tell you really want to make it work out. *** I just wanted to clarify that just because your tank is cycled doesn't mean its established. An established tank is a synergy of (organisms and bacteria) your water, sand, and rock that hits its optimum level at around roughly six months.
