":- 1 inch of fish must have at least 1 gallon of water. :- Every tank must have a permanently running 'cycled' filter. :- Every tank must have at least 50% of its water replaced every week." Each species needs their own special water parameters and failure to provide water of the right temperature, pH and GH will also make the fish sick as will failure to feed the fish the correct diet.
