Snails - not really a disease but certainly a pest!

Recommended Posts

I have a snail problem - it is getting worse by the week.

I am not sure how to cure this problem. I have 3 large yo yo loaches

When they were small they seemed to control the population of snails, but now they are large they do not seem to control anything.

I do not want to buy any more fish but I would like to control the snails which as you can see are everywhere.

Reduce the feeding, the main reason you get an outbreak is that there is over feeding/food left over for snails.

And from the looks in the picture it looks like you have Malaysian trumpet snail that are harder for the fish to eat then other snails.

I had a problem with snails a while ago, and I scooped as many as I could with a net each night (though they did get cunning and hide after the second night) and reduced the population that way.

Hope that helps

if you want to try and get rid of them completely, and have no other invertebrates in the tank, you could try dosing with something like AlgaeFix

(or if you just want to reduce the numbers, take a few out, dose, then put them back in a week or so later)

..........Why put them back if the idea is to reduce the numbers? :-?

cause if it kills them all then there wont be any :) Sounds as though iisfaq is just after a reduction in numbers, rather than total elimination

interestiong point re: Loaches eating dead snails... would have thought it would be ok, as it is a water borne medication, rather than 'snail bait' so the fish wont get anything they arent getting anyway?

I used it recently in a small minnow pond to get rid of some hair algae with no problems. The Fish were fine, and I imagine they would have been eating a few dead invertebrates

Then take out less. You'll never, within reason, be able to manually remove all of them anyway.

I was talking about putting 10 (or whaterver) back in after you have killed the ones in the tank...

Thanks for the suggestions.

Food is probably an issue so will reduce - have been away and someone else was feeding so they probably overfed as well.

I would like to remove them "all" but a reduction by 90% would be nice.

The tank is about 300 litres...

thanks

There is a product called snail rid I think. Copper sulphate or something..

If you could house your fish temporarily in another tank and then blitz the main tank with snail rid and once treatment is done do a few big water changes and introduce fish again..

You might kill off some of your plants too though so if there are some plants you care about a lot then take those out too.

Dangle some pieces of courgette or cucumber in your tank and pull them out when they are covered in snails. That works well. I have also found that MTS love shrimp pellets, pile a few in a corner and net the snails out with them when they come to eat. Other option is to borrow some clown loaches - they will get rid of the visible population but there will still be some turn up in a few months.

Normally early morning, just before light the snails come up towards the top of the tank - if you can grab as many as you can each day that will also help.

Don't put them back in. They deserve no mercy. Strike them down! Follow them back to their bases and kill them, all of them. All of them! No mercy!

I had good results doing as you suggest - took the fish out and nuked the tank with copper sulphate. The snails died within minutes, I did two complete water changes, then put the fish back in. Plants and bio-filter were fine.

I was snail free for about a year, until some eggs managed to sneak in on some new plants. I'm not over-feeding these days, so haven't bothered nuking again - there's only a few snails and they don't seem to munch plants, so it's all good.

You can get copper sulphate at Bunnings in the plant fertilizer/spray section. It's frequently called bluestone. Costs bugger all for enough to last a lifetime for anti-snail duties :)
