Also question is, what is the best thing to put on the bottom of a fish tank?
Gravel is the better choice for most freshwater aquariums. One of the major benefits of gravel is that it allows water to flow through it, preventing the buildup of amoebas and bacteria in the substrate. If allowed to build up for too long, these can sicken your fish and lead to an accumulation of aquarium mold.
