Fish help!!! Cleaning, Feeding, and basics.?

Get them a 10 gallon tank(Because they actually need it) and buy a over tank filter for it, it shouldn't be that expensive. Also, if you really have no time to clean it, just buy a small algae eater, like a small pleco or a Otocinclus. They will keep you're tank fairly clean, and if you get a good filter, it should keep you're water crystal clear.
