wow! tank 75 , trade in I don't want to change myself I watched my yelllow tang grow butt! my husband Rory is insisting on changing , he wants one of everything! so I will leave it up to the poll to help me make my decision the tank is a 75 for now but I will probally upgrade in a few years to a 90 ( Jeremy would hate me for changing to a size that my new canopy/lighting won't work in lol) so keep the opinions comming Dave I totally agree , but I have to make my husband happy somehow since he takes care of buss. like the electric bill!!!
