Is this coloration normal on Mystery Snail shell?

Hi, I've had my mystery snail for about 2 weeks now and he's grown quite a bit. Is this color change on his shell normal? He seems happy, moves around a lot & eats well.

I feed him spinach, zucchini, and algae wafers. I know he also eats the leftover sinking pellets from my pearl danios.

I just want to make sure something isn't wrong 😬

When they are being raised, often they have a really mineral rich environment, possibly optimum water hardness, great diet. When they go to a new home, the water and foods are different and then their shell will change color sometimes lighter and sometimes darker.

So it is a normal occurrence. Just take a look at the new shell, does it look strong
or very thin? What mineral content in the water, especially KH / calcium / alkalinity.

You can make adjustments if you notice any issues. If needed you can increase the calcium in the water, feed a shrimp or crab food with the necessary minerals and dietary requirements for an animal which needs to produce a shell.

Not too long ago I had Blue Mystery snails and for some reason the shells became more blue in my tanks. I will supplement them with Hikari Crab Cuisine and have a Cuttle bone in the tank too.

But they eat all foods/ leftovers whenever possible, covering the food with their massive body. Before that I did notice with one group I purchased they had been in harder water before I got them and I noticed shell erosion from my low / almost no KH tap water (when I had stopped using a calcium additive to see how it went with my pH and tank stability).

Kent's Marine Superbuffer dKH is what I have used, and it is fairly low priced. I got the larger container maybe 2x the size, for not much more than the smaller container last time.
New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
