Welcome to the forums j-dubs, and don't be discouraged by old fuddy-duddies ?
Adhering to the law is a foregone conclusion, that doesn't require parental intervention.
When I was your age, I had 2 bass in my aquarium (Shocking as that may appear!!).
My 2 bass would be best described as fingerlings, but received my undivided attention.
At that time, I would've guessed they subsisted about a year in my tank,
but through the compressed lens of advanced age, it was probably closer to 6 months.
Be that as it may, there were no ‘Fish Police’ in Hillside, NJ,
and it was not a bad experience ?
