The best tank? That's easy: A fish tank!
They rock dude. You can put water in them and a filter.....and FISH! You feed them (not too much as they over-poop the water and make it kill them).
You watch them like the wild kingdom. Some will die...others, if group them well, will eat a tank-mate.
Or.....you can empty the tank and dry it and throw a reptile in there. A nice ball python? Or some kind of lizard? Something that requires food
from the pet store. Like the ball python....depending on the size, a mouse a week or gerbel per week or one rat per week. That's cool. Watching
the poor little rodent walk around without a clue and either get it quick...or, the snake decides to wait a day...or two and that rodent is now
shaking and waiting to die. It knows it's over. Just don't take a rat out and make it a pet. Because they actually make cool pets. But, if your
friend a month later tosses it into the tank with a hungry python, the python will eat it...and probably not move for two days as the big lump in its
belly gets smaller and smaller.......and you have to say goodbye to Ricky the rat or whatever you named him.
But seriously, I hate to see fish in fish tanks. They should be free in whatever water they prefer, not in a tank for our amusement. How would you
all like it if giant aliens came down and put you in a tank for their viewing pleasure. There was an old Twilight Zone episode that touched on this
subject.
I hate reptiles too....the snake thing happened about 15 years ago and it was a friend's snake. Most certainly NOT mine!!
