Saltwater aquariums

[Skelas]

I'm a proud owner of a 55 Gal fish only with live rock saltwater aquarium stocked with 2 Perc clowns, royal gramma, flame angelfish, a lawnmower blennie, and a cleaner shrimp. Anyone else partake in this stupidly expensive hobby? I'm relatively new to it so if anyone has any history/experience with saltwater tanks, let me know! They can be a bit of a struggle, believe me.
