All home aquariums need some sort of substrate in order to build up a bed of beneficial bacterias. Alot of problems will occur without a bed, however it is possible to do a tank without one. Though I would never recommend it.

What type of filteration system do guppies need in a 5 gallon aquarium?

A simple air driven corner filter should do the job in a tiny 5 gallon tank provided the tank contains no more than 3 guppies. The first basic rule is :- 1 inch of fish needs a minimum of 1 gallon of water. Your tank is nominally a 5 gallon tank which means when it is only filled to within an inch of the top and has gravel on the bottom, the most it will be holding will be around 3.5 to 4 gallons of water.


How long do guppies live in a 10 gallen tank?

It depends on how many guppies, and how well you keep up the tank. In a ten gallon tank, I'd say no more than ten guppies, and do frequent water changes. 10-15% weekly. They need a filter and a heater, as well.
