Aquarium Advice Addict
Our 20g has several new things including red flatworms but this thread is about something stranger. Several of the rocks are being colonized by some red ball shaped things. Most are round but some are flatter, they have a white line across the tops from one end to the other. Some of them remind me of shrooms but they are not flat but circular top to bottom. Sorta remind me of green bubble algae but feel more like corals. I guess the white line across them is the weirdest thing. I'm pretty sure I can't get a good picture. Any ideas.
