Arvin, I'm so glad to hear that you have small snails living with your Aldrovanda! They serve a multi-purpose function and are essential for a healthy population of these plants. They actively graze on the algae that attempt to anchor onto the Aldrovanda, and also are vital in pulling out the spent prey in the older traps (which otherwise would get loaded with filamentous algae), as well as providing an occasional meal for the plants, and also help contribute to the CO2 within close proximity to the strands. Perhaps you have some copepods as well, along with other small crustacians along with live tubiflex worms and Daphnia. If you look at a healthy strand of Aldrovanda under a disecting microscope, you will notce that it's a floating zoo, full of life crawling all over the leaves, and up and down the strands, from small insect larvea, (including mosquito, and damsel fly) to snails, and crustacians, and several small worms.
Good job! and Well done! - Rich
