It's alright. My sister and I just went from 12 bettas to 16 in the last day. 5 males and 11 girls, but at least the girls are in sororities, the males are harder to accommodate. And, we haven't told our mom or dad yet. They didn't even know about the halfmoon with a tumor that my sister bought about a week ago. And they didn't know, but soon found out, about the sickly new crowntail I bought a few days ago.
To be fair, we are trying to set up a new home for my sister's first male, since our uncle wants a fish, but our grandma keeps flip-flopping on the answer. We're being very strict with housing for him though since he's a huge veiltail and we don't approve of the betta tanks sold at Walmart or Petsmart. Minimum we are allowing is 2.5 gallons and my grandma's iffy on that.
