Y'all. My pagoda snail eats BBA.
This tank has been running since 2012, with black brush algae nearly its whole life. I went through a period of neglecting my tanks, and the bba went into remission with dimmed lights and low nutrients (one lonely nerite).
Recently I got more motivated to care for my tanks, upped the lights, and bought some shrimp and pagoda snails. The bba came back with the lights, as expected. The snails have been going after the algae on the glass and crypt parva for about 3 weeks. Then yesterday I saw one with his nose in the bba. I thought he was looking for bits of food in it, like the shrimp do. Then I saw the clump of algae looked a bit trimmed. Thatís the first photo, the second is the next day. He ate it!
Tonight I caught him at it and had to share - third pic is him chowing down, fourth is when he moved on, and fifth is the bare nubs of bba left in his wake. (Sorry, don't post a lot of photos, so I don't know how to mix them in with text like captions)
This is a game changer for me. I have bba on the hardscape in all my tanks - they are all low light, so it stays in balance with my plants, but it would be awesome if these snails could help reduce it.
