MTS genetics are all over the place cause most populations are seriously inbred. That looks like an adult, and once they get bigger they generally start displaying less color, which can look awesome, like yours does. You lose the browns before the reds,
I don't know why but Aquatic Arts used pics of their inbred stock versus the 400 beautiful snails I sent them.
There's black MTS, I don't know if they can crossbreed, I don't know that I wanna risk it with my breeding group.
I've spent like 20 years introducing new genetics and culling. I'm getting bigger sizes and better pattern retention. I am a crazy person lol
There was someone on another now dead forum (Aquaticfreaks? or something, they showed off weird fish morphs), who had a population with spikes, but the tank they were in was dead and gone by the time I messaged them.
It's 100% worth your time to cull smaller ones with less color or stumpy shells and also hit up fish stores and ask if you can harvest some of theirs to increase genetic diversity. In my experience they'll just grab some of if they know you make you do it yourself.
Also if you're seeing them when the light is on your tank needs a water change or you need to seriously cull them and feed less. Seeing MTS on the glass is like the canary in the coal mine passing out.
Sorry this is disjointed, I am currently very sick. Please feel free to ask questions
These are super old pics, from when I was just trying to lock in the bigger size, before I really got into the patterns, but you can see how the color loss progresses.
So yeah you just got an old snail and also I think you should do a water change <3
