Freshwater limpets are taking over my tank. What’s the best way to control them?

I have a planted freshwater aquarium, and somehow freshwater limpets (Acroloxus lacustris) made their way into the tank. They must have hitchhiked in on plants because I definitely didn’t add them on purpose.

They don’t seem to be harming my fish or shrimp, but their population has exploded and they’re everywhere—glass, hardscape, even the plant leaves.

I’ve read that pea puffers (Indian dwarf puffers) will eat them, but that’s not really an option since I keep cherry shrimp and other peaceful fish.

For those of you who’ve dealt with freshwater limpets before, what worked best for reducing their numbers? I’d prefer to avoid using chemicals if possible.

Thanks in advance!

1 Year 4 Months Anubias Nana Aquarium – Stable Growth, Recent Rescape & Transition to a Larger Tank

https://www.reddit.com/r/Aquascape/comments/1p7wv9d/1_year_anubias_nana_aquarium/

It’s been a few months since my last update (originally posted on November 27, 2025), so I wanted to share a small follow-up on the tank’s progress.

Overall, the aquarium has remained very stable. As expected with Anubias nana, growth is slow but consistent. New leaves continue to appear occasionally, and the older leaves are still holding up well with minimal issues.

Algae has stayed under control with regular maintenance. I previously experienced a short period of green spot algae, but reducing the lighting duration helped stabilize the situation. Routine water changes and occasional leaf cleaning have been enough to maintain balance.

Since the last update, I’ve made a few small changes. I completely removed the background plants, as they weren’t thriving well in the limited space. I also trimmed and removed a few Anubias nana plants as part of routine maintenance and reshaping.

There aren’t any major changes planned at this point, as I’m preparing to move this setup into a larger aquarium soon. Because of that, I’ve kept interventions minimal and focused on maintaining stability rather than redesigning the scape.

Looking back over the past year, it’s interesting to see how slowly but steadily the tank has matured. Even without dramatic changes, there’s still a clear sense of progression over time.

Thanks for following along 🙂

5-Month Update – Utricularia graminifolia Carpet, Red Diamond Bloom & Corydoras hastatus

It's now been about 5 months since planting Utricularia graminifolia. Over that time, I've trimmed it three times, and it's gradually developed into a much denser, more established carpet.

One surprise during this period was Nymphaea sp. 'Peru Puerto Maldonado'. It completely disappeared after the initial planting, so I assumed it had died. Then, around the 4-month mark, it unexpectedly emerged again. It was a nice reminder that some plants simply take their time.

My Echinodorus 'Red Diamond' has also been doing well. It recently sent up a flower stalk, and there are now two flower buds developing.

More recently, I introduced a group of Corydoras hastatus to the aquarium. They've settled in nicely and have been a great addition to the tank.

Overall, I've continued to keep maintenance fairly minimal, allowing the plants to grow and stabilize naturally. Watching the aquarium mature at its own pace has been one of the most enjoyable parts of this setup.
