Water Sprite takes over the world!

17 Oct

A few months ago I found a thumbnail-sized plant floating in one of my aquariums. I still don’t know where it came from, I hadn’t bought any plants for a long time.


It was a little Water Sprite plant. I hoped it would grow, expecting it to get maybe 3 or 4 inches across.

It grew…

CAM01438…and grew…

CAM01419…and grew.


Eventually, it started reaching out of the aquarium. It’s leaves take a different fern-like form when they are above water.


This thing is crawling out to get me! Help!!!!


The main plant covers half of a 55 gallon tank. It’s 24 inches across!!

Also, the plant forms baby plants along the big stems and I have many Water Sprite plants now and have given some away.


The Water Sprite can float or be be planted in the gravel. It’s leaves are soft and the snails will eat some of it. I crush the snails and that makes my Angelfish and Swordtails very happy.

CAM01596If you look up Water Sprite on the Internet you will mainly see reference to a fine-leaved variety of plant called Ceratopteris thalictroides. I believe my plant, I mean PLANTS, are Ceratopteris cornuta, which is the broad-leafed Water Sprite, even though it sounds like a dinosaur.  I think both varieties of Water Sprite take the same care: Water, light, fish poop.

    So instead of a green thumb, you must have a wet thumb!

      It’s been fun to have such good luck with the plants. I think they are a major key to keeping fish. Now I think I would find it difficult to keep a tank looking nice without them. I would need stronger filters and I would be scraping the glass all of the time because if there aren’t plants there will be more algae.

    We’ve got java fern that has to be thinned every few months. I love having a heavily planted aquarium!

      The first time I tried Java fern it slowly died and I was puzzled. I heard that it grew like a weed. I got some more a few months ago and it ‘s doping pretty good. I should take some pieces out and start them in my other tanks. I have read that it like to attach itself to wood which many of my tanks have.

    Wow. I wish my water sprite would do that. Mine is slow growing. But don’t get me started on my java moss. It’s unruly.

      If I have 2 light bulbs over the tank the plants go wild. One bulb and I grow Java Moss.

    OMG. I have been looking for the ceratopteris Cornuta for years! No one seems too carry it. I had it in my aquariums when I was a kid. Where can I buy the Cornuta?
