hey all,

just a general question about snails. i know most people favor the malaysian trumpet snails for keeping gravel fresh and not eating plants. i had a good crop of maylasians, but they got wiped out by a new breed of snails (accidentally introduced), round without a protruding spiral. these new snails dont seem to eat live plants but do eat dying leaves.

my question is, if the snails dont eat live plants but do eat dying leaves do you think this would be good or bad for overall water quality. which would contribute more to bad water quality, the decaying plant leaves, left uneaten, or lots of snail poop?

thanks for your 2 cents

Please tell me about this "new breed of snail". I thought nothing short of a thermo nuclear device was capable of getting rid of MTS's.

To paraphrase RTR, the snails are converting debris into snails and waste. You can either export the debris yourself or export it as snails. The waste from the snails gets used by plants and bacteria.

Personally, I hated trying to vacuum debris out of the tank, I find it pretty easy to pick out snails and I can wait and let it build up until they are noticible, then pullout a hundred or more.

And Doomer, you can suffocate a MTS. They need air every day. Put them into a cup with no air space and they die a nasty death. NOt me, I didn't do it, but know someone who does them in this way.

They must be able to hold their breath an awfully long time since they spend most of their time burrowing in the gravel and move pretty slow.

I recent had the kid pick them out by hand and he got what looked like hundreds of them. A couple of hours later and you couldn't tell any were missing. either they breed rather fast or half the substrate is snail.

btw, Ghori sent me 10 of them about a year ago and from these sprang forth millions and millions. They'll be around as long as there is water on the earth.

doomer,

sorry i cant add much to the "new breed" description. just round, narrow, shells that dont protrude into a spiral. mostly dark brown in color. im not at home now, but maybe i can get a pic for you soon.

if you want to try some i will send you some in exchange for some mts, i need to try and repopulate.

My daughter has picked some out of her betta tank and put the snails into a plastic cup with a small amount of water, then pushed another cup onto that so that all air is excluded. She reports that they die in 24 hours, stretching their neck out as far as possible to try to find air. This agrees with the observation that in tanks where there are snail eating fish, the snails all come out at lights out to go to the surface. I do not know if larger snails have a larger store of air after surfacing, but I guess that t if they do it is balanced by a larger need for air due to body mass.

Sounds like ramshorn snails.

I have them and they do just eat the dying material. THey can get way out of hand though, I have to take out a bunch every so often. But, they keep my tank rather clean & I don't mind them too much.

Yes they do sound like ramshorn snails. As for suffocating snails i must admit I have never heard of this method of elimitating snails but it certainly sounds interesting. One thing that could be a problem is that you have to totally deprive the tank from light because plants produce oxygen in light. Even if you reduce air from disolving into the water by taking out that air-water exchange point, the plants could still be putting dissolved O2 into the water. So I guess it all comes down to how long can the snails last with the existing dissolved oxygen, and would they last longer than plants would without light?

For a more easy way to eliminate the snails, just put in one clown loach (or more depending on the severity of the snail infestation). It will be more than happy to eat them. Another good fish you can use for the same job is dwarf puffers. The advantage of dwarf puffers over clown loaches is they never grow big, but they are more rare and harder to find.

I don'[t know if suffocation would work on anything but the MTS, and I don't see how to do it without simply picking them from the tank. But, I thought I'd put that little fact out there, as from time to time I see someone claim that they cannot get rid of the MTS, even after removing gravel from the tank and chemically treating it or something.

I love it when people contribute something like that. Honestly, who would have thought of suffocating snails? I think that was a great contribution to this thread whether it actually works or not. Thanks.

Maybe a cap full of mineral oil would accomplish the same thing. You'd have to remove the fish first, of course.

I have read about people so desparate to rid their tank of the snails that they removed all gravel to a bag outside and let it sit in the sun for a few weeks. Upon returning it to the tank and adding water, the MTS reappeared.

Knowing that they can be suffocated, that same bag of gravel removed from the tank, filled with water and tied to exclude all air, might have done them in for good.

Pond snails, ramshorns, or other snails might have been killed by leaving the gravel to dry out.
