That is a real beauty! Brian IX?
It's all a bit confusing...there's some mixup about a mystery snail being an apple snail but not all apple snails are mystery snails, including the legality of each. Interesting ID, Autumnsky...I'm ready to go with any identification. My local Fed WLFS classifies Pomacea Canaliculata as the large species of apple snail and is illegal to sell or transport in many states and countries because they are invasive and spread parasites.
They classify mysteries as Pomacea Diffusa. Periodically the Federal Wildlife & Fisheries Service activates their ban on P. Cana to a higher degree and turns a sharp eye on the pet snail trade, casting a wide net to include anything in the Pomacea family. Even legal mysteries that we've been happily buying for years.
The most recent time was about two years ago. This is how that worked out, in this state and number of others:
We went to a favorite LFS to buy another mystery but suddenly the snail tanks were gone. When asked, employees gave us the stinkeye and brushed us off with "We don't carry snails. Never have". It was the same at another favorite shop, only instead of dismissive they looked scared, like we were the snail police come to lock them up. Both places gaslighted me, backtracking to make sure I knew they "never" had mystery snails.
In desperation I ended up at a big box store, and there received a stern lecture that shed light on the situation: "Apple snails are highly illegal and are not sold anywhere and never have been, per federal law". Never mind that I was asking for a mystery snail.
So I did meet the Snail Police and, incorrect info aside, he basically introduced me to the ongoing ban, seesawing between activated-not activated/in one state but not another, etc. Looking around online confirmed that this was indeed going on in other states.
We were suddenly looking at our snails with a question mark: Are you legal? Are you what you were when I bought you? Am I supposed to "turn you in"? To who? A restaurant?
One month later I went back to the same stores, and everyone had mysteries for sale. No problem, as though the snail alarm had never been rung. And so it goes: one month Brian's peacefully putting along as his own mystery self; the next, he's a criminal in the Apple Gang. Congratulations on your new family member, whatever we may call him
