btw are there any ways to win ur parents over. My dad says fish grow to biggest size no matter wht size of tank.....I was like seriously. No they only get so big. And it causes problems if there in too small of a tank.
Vacuum the house. Clean your room. Wash the car. Yard work. Bust your ace. If my daughter did any of the above without me telling her to, I'd probably have a heart attack then buy what she wanted.
