Cyanoacrylate glue is a safe adhesive for bryozoans; aquarium silicone works as a strong and flexible glass adhesive, but requires curing and conditioning before use. If tank aeration is used, ensure that colonies are placed away from the bubble stream, and away from the strong flows generated by submersible pumps and inlets. ].
