We did not become people who have fish as pets voluntarily. One of my wife’s coworkers ( JEREMY ) gave our son a goldfish. 4 goldfish later, we tried a betta. 3 betta’s later, we found one that would live for more than a week, but had to move it to it’s own tank because it didn’t get along with the snail we go to clean it’s tank.
After several combinations, we are down to this; a frog and two tetras. These are the ones that refuse to die no matter how scarce their foot may be or how old their water is from the last change. They are the Mad Maxes of the aquatic world.
