KEEPING FISH ALIVE
Do Not Over Crowd The Fish
I cannot stress this enough. Fish need space to swim. Fish are living breathing things. All fish are not the same.
Fish Need Space To Swim:
Let us begin with the original accepted guideline of 1 gallon of water = one inch of fish.
This means that in a 10 gallon tank you can house 10 inches of fish in a bare tank with no gravel. Remember that gravel, and decorations take up space. We need to allow for that space by putting in fewer fish.
