I have a 5 gallon aquarium with about 1 inch of gravel and 6 tropical
fishes (1Guppy, 1platy and 4 small neon), and only have plastic plants. I
have a filter that hangs ou side the aquarium, with carbon and sponge in
it. I do weekly 20% water change. I want to know is it absolutely necessary
to clean the gravel in this aquarium? And if so how often it should be
done?
==================

Some people claim toxic gasses accumulate in the gravel, especially if no
live plant roots are running through it. I do have live plants in all my
tanks buy vacuum the gravel anyway. How often depends on how many fish I
have in the tank and if I can see mulm on the gravel or seeping down into
it.
