• Unidentified algae, please help identify.

Here are some green sticks, and I can't figure out what kind of plants they are. If anyone knows, please let me know. In the second photo, there's a small white bag with little tendrils, about 7 millimeters long. What kind of wonder is that? Thank you in advance to everyone who responds.

The sticks are calcareous algae Neomeris sp. When a whole bush grows, it will be beautiful. On the right in the photo is the sponge Sycon sp., its presence in the aquarium is desirable because it acts as a filter feeder. However, the filamentous algae around the sticks need to be removed with a stiff brush, as it will hinder their growth.
