Dennerle Snail Catcher - for Aquariums, with Telescopic Handle

So bear with me for story time, if you will. Somehow a single snail (one) got into one of my aquariums, I assume by hitching a ride via a snail free plant. Despite the fact I've been around aquariums my entire life, having three aquariums set up currently (35g, 75g,and 90g), ignoring that I know it only takes ONE snail to ruin everything so I Should Not Do This, I very foolishly plopped it in my 35g aquarium. Human hubris, I'll admit that. Now, depending on fish stock and tank size a very simple solution is to get a minimum of five+ Corydoras (they shoal my friends, happy cory are helpful cory) and kiss your snail problems goodbye. Seriously, the ground zero tank had that single snail for several months (I couldn't move fast enough to catch it) and thanks to the diligence of thirteen corydoras there are zero snails in that tank. No snail sightings, no sign of eggs, no moments of did the gravel move or am I losing it, nothing. Now moving on to the 35g. In a single month I that lone snail has created a massive infestation. There are eggs everywhere, snails of various sizes on absolutely everything, and A Very Upset About The Driftwood Eggs Bristlenose, it's awful. There are very few solutions to this contamination: copper (I don't feel inclined to medicate a tank of small fish in a feeble hope it kills the snails), remove the fish and boil everything (I'll never be able to catch them again in my larger tanks), snail traps (nothing suggests they actually work), or... Enter this purchase, which I like to call The Snail Squeegee. I have never bought something that is so deeply satisfying to use, to the point where I actually get a little excited when I see snails pop up on the glass. This product is very easy to use, doesn't seem to concern the fish whatsoever (my Dwarf Gourami likes to assist me by following my hand, he's offering me moral support), and seeing the snails pop off is delightful. I'm giving this five stars because I'm at a breaking point and this product very effectively makes Snails Go Away Right Now, but my only complaint is I have no idea how I'm supposed to properly get the snails out of the clear bit? Waving it around in the middle of the yard works, or a steady stream of water, so this isn't a deal breaker for me but maybe something should pop off for easy dumping? Unclear. I would also like it if the clear chamber part was a bit longer to hold more snails. After a certain point if I tilt to get one at an odd angle I have had an escapee a couple of times, but ultimately it's not a deal breaker for me. Now, that said, as therapeutic as this product is, it won't solve a longterm snail problem unless there's something to stop it at the source. Thankfully I have a team of pygmy corydoras who've been working overtime on egg consumption and I just might hire on some new recruits. Words of advice: If anyone has a snail infestation in a community tank, get yourself a very handy snail squeegee and five+ corydoras and you'll be golden. Or depending on your fish stock (ex: larger and/or aggressive cichlids who will just eat corys) just skip meals for a couple of days and they'll turn on the snails. A good gravel cleaner should also help with cleaning out eggs. TL;DR this is a fabulously satisfying product that solves part of a problem and the only thing that'd make it better is a bigger chamber for scooping up snails.

This snail catcher is pretty cool for a plastic device. I have been using it to remove snails from five different aquariums. Three are new setups without fish at present, and two established with fish. The established aquariums had a lot of small snails, but as I removed them, I am seeing less and less. The new tanks got snails from snail free plants. As I was cycling the tanks, I removed the snails as soon as I saw them. It has been a week since I have seen a snail in the new tanks. This snail catcher was amazing in its simplicity of use, and I believe it helped me in cleaning my tanks of invasive snails. I highly recommend this product.

a little fiddly, but it does work. you have to get used to the proper motion to pick up the little buggers without just knocking them off the glass.

I've tried lots of snail catching gadgets, mostly of the bait attracting type, and by far, this is the best for manually removing small invasive snails from your tank walls. The head of the device pivots so you can get to the snails at odd angles. The handle does extend to abut 1 foot. The clear catching bucket below can be pivoted to open for easy dumping out of the caught snails. To use, gently press the device under the snails on the wall, then gently slide upwards to make the white wheel roll and it catches the snails and dumps them in the clear catcher section below. It works very well and easy to use. It doesn't catch snails on plants on on the substrate. It's a bit pricey at $26, but it's well made from Japan, so hopefully will last a while. Overall a good buy and I highly recommend it and would repurchase if necessary.

Easy to use and maintain snails

I don't know exactly why something made out of 2 pieces of cheap plastic should cost $20,- can anyone explain?... Yes it works . Yes it's overpriced, but the alternative would be picking snails by hand , I guess ?... It's a great idea - but come on, it does not cost that much to produce it, the price is a rip off. It is not a "high quality" item, it gets all wobbly and not running smooth after few times and the lid doesn't close well but it still works for picking those nasty snails out.

Within weeks everything was out of control after moving the guppies to another tank. The shrimps RCS were fed little to nothing in the established tank but the few snails had were more too much food available and snails eggs were everywhere . When they “ feel “ the danger the don’t resist and sink and it is more difficult to catch a moving target ;)) Usually they were removed and given to koi & goldfish but this time it was impossible to remove enough and keep up. After few research I tried DIY technics, bought 5 different traps but the result not there. Remember, shrimps eat the same food as bottom feeder but the snails outnumbered the RCS. I looked the snail catcher, the high price put me off originally but after many useless attempts I decided to buy it and it works this snails on you aquarium glass. However I had to remove manually with a 16 inches forceps but it was not a big deal. It’s a matter of amount of food available and the right tool. It’s not cheap, it looks a bit fragile but it works very well. You won’t regret it. Ps: when moving the tool along the glass, you will notice that the efficiency is a matter of slow peace & angle in order to catch them .

This tool does not work. I have had it for years and it's been infuriating. The roller does not roll against glass!! I was hoping that the company would have redesigned it by now, since I know they know it doesn't work. DO NOT BUY!!!!

Natty little device that has reduced my pest snails infestation considerably. It has a sturdy aluminium, telescopic arm. It is expensive. But at the end of the day it works

Fungerar utmärkt. Enkelt att använda och det går att samla sniglarna snabbt. Lätt att tömma också. Jag är så nöjd!

Gemakkelijk in gebruik.

I have to admit when looked at the product online I was a bit skeptical particularly given the price but this thing is perfectly designed. Keep the arm fairly parallel to the tank wall and it works flawlessly. I mean flawlessly. It grabs the tiniest snail to anything smaller than... ~5-6mm. Its quick and easy to use and the little trap door makes empty the snails a breeze. I don't mind having a few snails to do some cleanup but this rig makes it easy to keep the population under control when I stupidly overfeed.
