I'm Deb and I am new to the site, although, I have read through many of the forums extensively. I inherited a 55g saltwater tank about 10 months ago, and have learned as I went. I have an Yellow Tang, black and white clown, a tomato clown, and a sailfin tang, clean up crew, an anemone and 3 Gulf of Mexico shrimp. I live on the Gulf of Mexico and the shrimp were caught in our crab trap, and I put them in the tank and are doing great and are wonderful sand sifter/cleaners. The tank is doing well but I do have some sort of algae? growing and I have researched and can't find anything that looks like it. Where and how do I post a question and photo, so those of you know alot more than I do, can help me identify it? Thank you in advance.
