Snail growth spurts?

[Crimson]

I'm no scientist but is there anything that can act as a catalyst to stimulate snail growth?

I recently bought some Spixi, Marisas and brigs.
The Spixi and Marisas were put in one tank and the Brigs in another tank.
Since the tank I put the Spixis and Marisas was a tad colder and out of curiosity
I put one of each in the warmer tank with the Brigs.

The spixi I named Spixels and the Marisa is named Ramses,
(he's king of the snails)
Here we are over a month later Spixels is the same size as the Spixi in the other tank
yet Ramses is at least triple the size of his buddies in the other tank...

Shortly after putting them in both tanks temps stabilized so temp isn't
a factor in his growth I can assure you.

We all know that Brigs develop and grow at a faster rate,
is it possible they secrete something like a hormone or enzyme
that could have made him grow at such an accelerated rate?

I'm just confused at how he's so much bigger, the two tanks are the same
temp, Have the same stats, similar decorations and everything.
There are virtually no differences between the two tanks.
They even both get the same food...
Algae wafers and fresh cucumbers.
(yeah, my brigs love FRESH veggies despite being told they wouldn't)



Here's a picture of Ramses along side one of the snails that came in
the same package as him...
You can clearly see how much larger he is by comparison.

Any ideas?

This isn't something I'd take for fact based on my own experience. Do you have a source stating otherwise?

Since the tank I put the Spixis and Marisas was a tad colder and out of curiosity
I put one of each in the warmer tank with the Brigs.

Temperature has a big effect on growth rate. When you state that the temperature stabilized, what kind of thermometers are you using, and have you checked to make sure that the temperature was exactly the same? I've seen as much as a 4F/2C degree difference between adjacent tanks for reasons such as water level and types of filtration.

How many snails total are in each tank, and how big are the tanks?

[Crimson]

I guess I was basing the Brig growth on my own experiences...
They seem to grow a bit faster and dye a lot younger then other species.

As for the temps, I've tried different thermometers and the waters levels are
always about the same, I try to make sure they are when I change them.

Also, do you think light may be a factor?
I noticed at a certain part of the day the tank Ramses is in gets sunlight
that the other doesn't get at that time.

Could these few extra hours of light make a difference?

Also, genetics plays a role. I have seen some snails grow three or four times as fast as other snails. The photos below show siblings born at the same time, kept in the same tank, fed the same food, water at the same temp, etc.....

Wow, those pics are amazing!
Suppose it could be as simple as that.

Also, didn't a make a pointless poll?
Maybe I forgot to add it...

Ooooh, I have one of those pictures too Robert! See these brigs Crimson? All from the same clutch, hatched the same day, raised in the same tank:

[Crimson]

Oh my, I guess the mystery is solved...
I had no idea they would do that!
He's just a big boy I guess.

It's kinda your fault Crimson--look at the name you gave him! He can't be a runt with a name like Ramses
