Mystery Snail Or Large Apple Snail

I know mystery snails are related to apple snails . And sometimes they do get mixed up,but in the state I live in , mystery snails are legal but the larger varieties of apple snails are illegal for it being a pest . So I would just like to know if this is just a large brown mystery snail or a larger species of apple snail . It was sold to me a s a brown mystery snail a year back . Here’s a pic of my questionable snail and my regular ivory mystery snail together .

 

Since I am in a state where it is illegal . I have never actually seen an apple snail so any help would be appreciated for ppl who have one or have seen one . And if it is , any tips on what I should do with it since it is illegal to have . Thanks

 

Depending on were you are they aren't illegal to have. Just illegal to transport or buy and sell them. Go figure. I'm not exactly sure how to tell the difference but a mystery can grow to the size of a golf ball and an apple to the size of a soft ball.

Heres the size of my two full grown mystery snails (yeah yeah, they are loving each other). Your other mystery looks young. And yeah, that brown one might be an apple snail. It looks bigger then it should be. Does it eat your plants?

 

My ivory mystery snails are a couple months to being a year . The bigger snail likes to munch on Java moss now and then but doesn’t touch the other plants

 

That snail is a bit bigger than golf ball for sure

It might get worse as he gets older and bigger. Either hes a mutant mystery snail, or hes a full blown apple snail, haha. My mysteries strip algae ect off my plants but never eat the plants themselves.
