    agreed, good fellas to have, and they often prefer lower light areas under the LR so if you see them dont turn the rocks over. they will often collonise a overflow area too and are good to have in there and sump, but most butterfly family will eat them very quickly in the DT

    I also have a lot of them. Firstly thought they are bad. But luckely previous threads on MASA all said they are good to have. Scypha Sponge or Hairy Tube Sponge.
