Allan B. Posted November 16, 2021 Share Posted November 16, 2021 I have no snails—only amano shrimp, celestial pearl danios, and a brittlenose pleco. May not be related, but I’m on day 3 of treating my aquarium with Maracyn, Paracleanse, and Ich-X. I also use Bacter AE to help feed the shrimp.

johnzhe Posted November 16, 2021 Share Posted November 16, 2021 Do they move/wave in the water and do they close up if you disturb them? Maybe they are a freshwater cnidarian, similar to hydra. (They have too many tentacles to be hydra though.) If they don't move, then I have no idea. Link to comment Share on other sites More sharing options...

lefty o Posted November 16, 2021 Share Posted November 16, 2021 looks like a case of the plant herpes. i have no idea what it is. Link to comment Share on other sites More sharing options...
Allan B. Posted November 16, 2021 Author Share Posted November 16, 2021 Update: After some research and asking around, this is likely a vorticella or zoothamnium boom caused by Bacter AE overuse. Basically, they’re feeding on the excess bacteria and they’re already starting to die off or get eaten by my cleaning crew. Link to comment Share on other sites More sharing options...
johnzhe Posted November 19, 2021 Share Posted November 19, 2021 A zoothamnium... hmm. Interesting. I used to have something similar in my tank, but I think mine were a bit larger and more active. Sadly they all died out.https://imgur.com/a/SGtDEWA The images aren't the highest quality, but did your creatures look sort of like mine? And Bacter AE overuse? I'm using that as well so I might have to watch out for it. Very interesting! Link to comment Share on other sites More sharing options...
Allan B. Posted December 3, 2021 Author Share Posted December 3, 2021 @johnzheYeah, that’s exactly what I had growing in my aquarium. I definitely have a small bloom when ever I use Bacter AE, so I’ve cut back to using it once a week. My Amano shrimp and pleco seem to get enough to eat without adding it to this tank, so I’ve decided to use it sparingly moving forward. Link to comment Share on other sites More sharing options...
