I'm not sure it would be legal for them to stock them. I think Alan has said before that it's technically illegal to collect them because they're covered under the crustacean harvesting laws?
Yup.
Actually, the red/cream male is for sale. I wouldn't be surprised if she has a buyer in mind already, her kittens frequently are claimed before they're even fetusses.
The tortoiseshell is going to be a queen though.
I'm not even sure it needs diluted, it's a bit saltier than the claimed ideal, but I had much better results before I started trying to lower the salinity to the "ideal" range.
Throw a couple female guppies in, that should calm him down. Soon he'll be too henpecked to want t do anything but sulk in a corner of the tank and wish someone would pour some beer in the tank.
Doesn't matter, kill them.
Doesn't matter, kill them.
No, kill them.
The only good snails are apple snails and you'd have intentionally put them in your tank. The rest, especilly for a new tank like yours are pests. Kill them.
You don't want a step down transformer, you want a 12v power supply. 12a is a pretty hefty amount of current, you'll probably do best with something like a converted PC power supply. Most others are either 1 amp range wall warts or couple amp laptop PSUs.

I'd be surprised if they didn't. The place I usually get rocks tends to have 3-4 large piles of a couple tons of different types of flat slate, schist etc. Like these couple pieces...
BTW, that would also require the seeds to be ground up into a fine powder, if they're not ground up they have too small of a surface area exposing it to stomach acids to release any cyanide. You'll just end up with lots of appleseed in their poop. Which is exactly the point of growing fruit around seeds. It would be stupid to kill the animals you want to spread your seed.
