Here are my problems:
1) When you buy a 15" fish and are worried he may be eaten by all your other fish.
2) when you refer to your 300 gallon tank as the small tank.
3) when your fish food bill surpasses your personal grocery bill for the week.
4) when you put your hand into a tank and know there is a possibility of getting your fingers broken by your fish.
5) every time your fish eat you lose 20 gallons of water from the tank.
6) As a general rule in your home nobody is to put their hands above any of the tanks...a=because you are tired of replacing broken tops....b= because somebody may lose a finger...lol
