I've been light hunting and I've run across legs before it just looks like they are brand specific. If it's a coralife or something similiar you might have a shot. Does it have holes where the legs could go or does it look like a metal leg slides out of it?

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
