Algae Eating Black Japanese Trapdoor Pond Snails are the preferred species of snail for recreational and professional pond and water gardeners world-wide. Japanese Trapdoor Snails are one of the few snail varieties that can over-winter well and survive in harsher northern climates. Japanese Trapdoor Snails are a great asset in helping keep algae under control in your pond and water garden as they groom plants, planting-pots and water garden rocks and walls. Japanese Trapdoor Snails will tend to the ponds bottom, consuming any decaying matter such as leaves, excess fish food, and even fish waste.
Black Japanese Trapdoor Pond Snails are live-bearing; they only breed a couple of times a year and will not take over your pond like other nuisance egg bearing snails can and will. In order for your Japanese Trapdoor Snails to have a positive effect on algae growth, a minimum of 10 snails per 50 sq feet will be needed, and farm ponds will need to have at least 200 snails to have any positive effect at all.
Please Note: There is a 5 snail minimum when ordering with other pond plants, and a 20 snail minimum without any plant order.

Mail Order: What To Expect
Snails may appear lifeless or dead from the agitation of shipping and will more than likely be hiding inside. Open the bag of Black Japanese Trapdoor Pond Snails; filling about half of it with pond water, then float or hold the bag for a few minutes and then let the snails slowly out into pond water after they have acclimated to the temperature change. The snails will slowly after time open up and move along. Leave them in a shallow area and let them work their way out into the deeper section of the pond or water garden.
Most Algaecides are toxic to snails and will kill them. Please be sure to read any precautions and instructions on any algaecide before you use it in your pond or water garden.
Black Japanese Trapdoor Pond Snails cannot be shipped to CA.

"Coolest little creatures ever!!!"Sheri of Champaign, IL
So happy and intrigued with these snail. It is very cool that they close up when I need to change the water. It's a little piece of insurance for my fish.View entire review
"These snails are cool!"Dan of st cloud, MN
I love these snails! They have definetly improved my aglae problem. People that come over and see my pond are amazed at them as well!View entire review
"Surprise success"Brenda of Orlando, FL
I thought I had failed with my snails. I put a few in each of 3 small pond/water gardens. I think the 3 with the turtle became dinner for wildlife. My chichlid killed the 2 that I put in her tank. (It was stormy when they arrived so I put them in my 2 aquaria until I could put them into their ponds.) I thought only about half of my dozen snails had survived. Today when I checked one pond I found 2 new babies! I'm thrilled! They're adorable. Apparently if they're reproducing they're happy in their environment. The babies are perfect little images of their mom and they seem to be healthy. Adorable!View entire review
"Black Japanese Trapdoor Pond Snails"Gerry Marrs of Priest River, ID
They have a face only a mother can love but these guys are great. I put them in a bowl with pond water for a few days and once they are moving around I put them in the pond. They take off immediately and start eating the alge. I have more fun with these guys than with my KOI.View entire review
"Common Pond Snail"Kami of columbus, OH
These snails are probably one of the best snails to keep in any tank, any size, so long as you don't put too many in. They are plant eaters, but they mostly stick to algae instead of lilly pads or floating plants. The do reproduce decently fast though. If your looking for snails to put in your pond to reduce algae levels these are your snails.View entire review

"snails"linda of addison, IL
Most arrived dead. Perhaps I have 5 that survived out of 23 that were shipped. You did send extras to cover any dead one, but only 3 extraView entire review
"Never Saw Them Again"CN of Richmond, VA
I followed the instructions that came with the snails EXACTLY. I put them in my pond months ago, and have never seen them again. ***Response from The Pond Guy..Snails are great at getting mixed into the rocks and gravel in a pond and blending in. If you haven't seen any empty shells floating around the pond there is a good chance they are still down there doing their job, even if you can't easily spot them.View entire review
"Hardy Little Guys"Tom Remar of Athens, GA
In the spring I put my 20 snails into my outdoor pond, over time finding several empty shells. :( There were no snails to be seen. During the fall I had to search the pond for some aquatic pets that would not last the winter. In the bottom of the pond were dozens of snails of different sizes. They are a lot of fun. I am going to try to put some in an aquarium in the spring. THink aquarium life will agree with them? tom "*** Response from Pond Guy-" The Trapdoor Snails should adjust to "aquarium life" quite well.View entire review
"Snail Catch 22"Jim Sturdevan of Knoxville, TN
Once you put snails in you cannot use algaecides as this kills the snails. So until the snails can reach the numbers required to make a difference you will have green water....View entire review
"Snail Mail!"Kay of Kingsort,
I ordered 30 snails and received 33 with the added bonus of 22 babies obviously delivered during delivery! All but one adult are speeding along at a snail's pace cleaning my pond! The babies are in an aquarium and growing like weeds...okay, that's an exaggeration. But really, I'm very pleased!View entire review
