If the house of a mouse in a 10 gallon aquarium, is it necessary to put an air vent in the tank?

I wonder if you need to put cover the air vent or higher if that is the home of a mouse. They are really small, so I want to know if there's a good chance to escape them or not? or a hamster. I know you can. But if you do not put a top of the screen, there would be a great opportunity to escape from them because they are so small in size compared with the tank? I know that mice do not live that long. But I would still like to have one as a pet. I used to have one when I was younger and loved it. (: Me too I am responsible for what he does not care.

YES! No matter how many beds to put there. Mice dig and move around bedding, mounding to sides and be able to jump. Will go up next to the water bottle. You do not want a bowl of water because mice can drown (I came into work more once to find the mice were drowned in our pet store) and put bedding and food in the water causing it to be changed several times a day. Get a bottle glass of water, however, that plastic is chewed. They also need a wheel to be used as a ladder to jump. Put a lid on the screen with the fixation clips in the top of the tank and check often for small holes chewed mouse. Mice jump very high. If you do not want to bother with a screen get a 20H (20-gallon tank high, not much.) mice live an average of 2 years. Hamsters an average of 3 years. Hamsters are easier to get and maintain but the mice are easy to train as well. Good luck and have fun!
