My friend has this fuzz ball in his tank. From looking around I see a few pellets that weren't eaten so I am leaning towards a fungus. Anyone else have any other ideas?
I'll post a picture in the next post so there isn't a link
I have some round sponges without "crowns" on them. They have kind of a yellow tint to them. The pineapple sponges look like pineapples.... these look like rotten oranges. Most sponges i have seen have some sort of "breather" hole. Does yours have one? If not then I would assume its probably a pellet covered in fungus.
