Okay, so I am new at this dont laugh. Can coral grow in a tank if no other coral matter exists in a tank? This week little white fluffy things emerged all ofer my tank. At first glance it appears to be a fungus or algae. However, a closer look shows a tubular organism with a slight crown, surrounded by fuzz. I am wondering if this is an emergence of coral or some other life form. I once over fed my freshwater fish, and the food became a white fuzzy fungus, but this is so different, and the fish have been underfed this week. I really cant get a picure of it. Can anyone help me figure this out?
