there are pros and cons to both. Mine live in bars and I had to buy wire mesh to put over them, because yes they could get out (it's a crittertrail one) when they were younger. They can't do this in an aquarium so that is an advantage.
In aqauriums the contain the smell better than the bars, but the smell can make your mouse sick, so you need to clean more often. Everyone has their preferences..I prefer bars cause I don't have to clean as often but as long as you don't let it get overly stinky they will be fine. I have two girls and I use a recycled paper kitty litter for their cage, it absorbs the smell really well and they love digging through it, and if they eat it it's safe. I clean their cage once a week. If they were in an aquarium I'd be inclined to clean them every four days or so!
Too lazy to even think of a siggy
