This started off small and I though it was some kind of coral. But now it has spread to the hole tank. If I just scrap em off will they just regrow. Also is there cleaner that will eat this. Sofar snails and crabs don't mess with it. Thanks any info will be great.
Some type of Botryocladia sp.possibly Botryocladia uvarioides.
