What Is This Sulawesi Snail?


Hello,

I am trying to figure out what this is:

I have many of these snails now because my sulawesi snails started to breed a few months back. This snail is born from Yellow poso snails yet it doesnt look like them...all snails born from my yellows look like this. i have about 30+ of these odd looking offspring.

I also have orange spotted poso snails in the same tank, so I was wondering if this mystery snail was a hybrid of the two:

The orange spotteds have two shell color morphs - one is the light tan you see here and the other is brown-black.
The babies coming from the orange spotteds do look like their parents (either tan or black shells and skin color matches):




^those three pics are orange spotted juveniles and a baby.

There is one more species of sulawesi snail in the tank, but its just one individual. is there a possibility that this orange poso is also involved in breeding?


So does anyone have any ideas?
Did something hybridize with something else, or do all yellow poso babies look ugly like that first pic, and then turn yellow? I doubt it.
Thanks if you have any opinions.

admittedly not a snail expert but the first pic looks like a trumpet snail with a smaller pond snail on top of it......easy hitchhikers

You know what? the most obvious thing has crossed my mind, but they actually do look like MTS...if mine do not grow any larger than 1" that would certainly prove it and explain why there are so many of them in my tank!

Looks like these internet pics a whole lot.
similar shell:


similar body color:


And yes the bladder snail in the first pic is obvious, sorry I didnt mention it. I was asking about the spiral snail.

My oldest one is larger than 1" I have had it for maybe 3-4 months. all the others are smaller because they have been born during the last couple of months. And this largest one looks like its not done growing at all. its would be surprising so see it reach poso snails adult size.

Are there species of MTS that grow larger than 1" ?
Here the big crazy question:
Could MTS be hybrids of sulawesis snails lol? or do the two just look extremely similar?

Some more evidence

For the MTS case:
These "hybrid snails" have the spiky mantle on the edge of their shells. looks like MTS have this too but sulawesi snails do not!

Against the MTS case:
After my yellow posos spent some time in the company of the other sulawei snails i have, I placed 5 yellows into my 20L. after about 1 month that one "hybrid" was born:

There were no other snails that were put into the 20L...strange that an MTS would spontaneously generate in that tank.

Those are FW hydroids, they're on rock, and yes since then i have removed all rocks and i dont see hydroids in my tank anymore. they're just as damaging as hydra but they do not kill any baby snails.

More searching, and it looks like some MTS grow up to 1.5" long!
Mine's not there yet so maybe i do have MTS with my rabbit snails.
so confusing...

Oh hmm. That's quite interesting. They look neat.

I like all aquatic life minus worms. So I am having a hard time bringing myself to remove my hydras.

Another question:
Is there only one species of MTS, Melanoides tuberculata?

No I believe there are different color variants. Between larger, smaller, lighter colored and darker colored.

I would have to take one! Which means they have to be out and about, lol. They are 2" or so, slow breeders. Not sure on their latin.


Typical MTS can get 1.5" easily, though they often don't when they have population explosions.
