We gave it a clean 200 gal tank, friends, food that it was really picky about (he only wanted to eat the tails of the feeder goldfish. We told him he had to eat the entire things. He refused. So we ended up having these three feeder fish with half missing tails called Breakfast, Lunch, and Dinner swimming around in the tank with our fancy fish because dumb old Oliver bit they butts off but wouldn't finish the job. Eventually Oliver died by flight, the tails finished growing back, we dug a pond, and Breakfast Lunch and Dinner moved outside to become our koi. 25 cent feeders. They got huge. Gorgeous. Size of my forearm. A friend who waited tables at a Japanese restaurant offered to buy them for the restaurant because he thought they were koi and not 25 cent feeder goldfish. We liked him so we said no, go spend your own 50 cents. He thought it was hilarious. Next week we went to get sushi and their koi fountain was full of feeder goldfish.
