are you honestly constricted to a 46? are you commited to a fowler, because i have a 46 reef with limited equipment, pc lighting, and my results are awesome! JK about the commitment part, although i would love a snowflake, but he would eat everthing i already have in my tank. you could go a juvi snowflake for a while, but you would eventually have to get a larger tank, you could go lionfish, although they also would get very big very fast, and outgrow your tank also. i think i see an upgrade in the near future!! lol
