I want to get a dog... does anyone here have a dog?

Is a dog better? Crabs are awesome!!! It can defend itself with its click-clack and snap-snap, it eats little (saving money is always good, especially these days), and it's very cheerful and friendly. Sometimes its friends come to visit: Lizard and Turtle x)

By the way, I also want to get a crab and a turtle in one aquarium, and in the second, a lizard (maybe a desert one, or maybe a swamp one, if there are any), and they will be friends and visit each other x)
