Okay, I've got a mature tank with some strange things starting to grow. I've tried to take some pics and label the items of questions. The first item is the appearance of burgundy balls growing on a rock. As the balls get bigger it starts to show a white cover on the top.(Item 1) The next thing I notice is the ball starts to have small holes in the top.(Item 2). Maybe going sexual? It does appear to be spreading. The third item is something that has been growing in the tank for a while and I'll just take some guesses at it. Thanks as always!!
