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.
no you should not
The amount of sand depends upon the design of your waterscape. I always have at least 3 inches of sand at the back and slope the substrate towards at least 1 inch deep at the front of the tank.
It is best to use pea sized gravel or sand. This is safe for them to eat as it will pass through them easier than gravel which can get stuck in their digestive system.
Red Eared Sliders are water turtles so they need water but sand can be in their tank with them. Sand tends to clog filters though, so gravel would be a better option.
hi I have 4 female and 1 male, All mine sleep at the bottom of the tank on the gravel while the lights are off but its not uncommon for them to sleep at the top of the tank, usually they perk up as soon as the light comes back on
This will depend on what you stock your tank with. You do not have to use any substrate at all if you choose not to unless you are going to have live plants, or if you keep rays that should have some sand to move around
The answer depends on the number of guppies. A few guppies can live in a 2.5 gallon tank or larger, temperature between 72 and 80 degrees Fahrenheit. Many people raise fancy guppies in 5.5 and 10 gallon tanks.
What are guppies
yes

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.
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.
