About the population relationship, you are very right. I have 3 major snail populations - cherry ramshorn, the small spiral ramshorn and the golden brown chut chut snail. Once, the cherry ramshorn dominate the tank, their populations were tremendous, and I see them reproducing all the time.
Later the chut chut came in, with some egg-infested plants and they start reproducing at the decline of the cherry ramshorn. Now its the chut chut dominating, and I have little cherry snails left.
It's quite amazing how they can compete at the expense of other types of their own kind. Kinda reminds me of some biology theory that 2 types of organisms cannot coexist at the same space and time. They may not hunt each other, but they will definitely affect each other.

Vinz, Andrew: Probably the stronger/faster snail get more food. The slower species slowly dwindle.
In my case the Malayan Trumpet Snails seem to dominate. Funny because they only come out at night in full force. Not sure why the RamsHorn snails seem to be dwindling. Not wiped out but population seem to have stabilised.

yes yes, actually MTS is a slow moving snail with respect to other types. Ramshorn, IMO, is still the easiest to bully, but they are still the purest type of algae eaters. Extremly strict to algae only diets, they are the most welcomed in any setup.

Resistance is futile, you will be administrated!
Food competition is one, maybe the type of algae plays a part too.
But if they compete for the same food, it does not make sense if the population fluctuates. I suspect the water chemistry plays a part... probably pH, KH and GH plays a part. Availablility of calcium perhaps? The population changes seem to follow changes in my fert dosing or CO2 injection rates. However, all these factors (i.e. algae type, availability of algae, water chemistry, etc) are all inter-related and there is no way to tell which is the real cause without scientific experimentation.
I also suspect if the snails prey on each others eggs?

Yea, that was also my initial deduction, I mean. Like the simple theory in biology, when a species in under threat of extinction, they will respond by reproducing more, to make up the numbers. Hence there shou ld be more hatchlings, but this isn't the case. Could be based on a predation of eggs?
Just a wild deduction.
Anyway, that chut chut is really a menace. I once destroyed 50 plus adults and young and they made up that numbers after 2 weeks.
Also they have a wierd habit of sliming their way up the tank every morning 15minutes after I switch on the lights. Like ants.
haha, this discussion is quite addictive! Snails!

kkkk........really addictive isnt it? if i get cherry shrimps will it do me good?(gettin rid of snails)Yea, that was also my initial deduction, I mean.

Nope. Cherry shrimps do nothing to snails.

What shrimps get rid of them then?
Hi, I don't think any shrimp has that capability.
In fact there aren't many options to consider when it comes to controlling snail populations.

Earlier in this thread Juggler mentioned Ghost Shrimps... look for the post, he linked the old thread about that.

Are yamato shrimps used to cleaning the tank? i got a few today
yamatos are used for clearing hair algae not snails.
