Not sure what these are good or bad.
Approx 3-4 mm long and egg shaped with a funnel like extension at one end. They are only growing in my sump and around a powerhead where the fish can't get at. Haven't ever seen them move or do anything nor have I seen anything go in or out of them. They appear kind of spongy. I don't think their hurting anything and their likely just a tasty treat for the fish but I was just wondering if anyone had any ideas about what they are. Sorry I don't have any pics my camera won't take good pics that close (I tried!).
