Hello my name is Tiffany and I’m a saltwater addict. I have had my saltwater tank for almost a year, I started with a ten gallon then moved up to a 20 and now a 40 gal. I have no idea what I’m doing however, the guys at the aquarium store said I’m doing great. I guess I have a good eco system going. I do have a question though. I got some new corals and I’m not sure if they are doing well. The pulsing Xenia looks funny. I got it today along with a green star polyp.(also looks funny)
