I've only got one aquarium though so I know I can't get both!
Well I could but the assassins will be asking for some garlic and butter to go with the mystery snail. Really beautifull creatures some of them.
My son wants a fish tank... I guess I could get him one and tell him he has to keep inverts first to learn to take care of animals...
... naturally it would be MINE ALL MINE... and it would become a snail tank! Then the assassins could go in the main tank to have a yummy bladder-dinner.
