How many....?

I think the most that I have ever added to a new tank, was about 30 neon tetras in a 48 gallon Bowfront tank that I had purchased used at the time. They were the first set of fish that I had added once it was done cycling, and the way they were playing made me almost want to keep them as a species only tank.

My first fish tank had 9 fishes. It's usually believed that it's lucky to keep 9 fishes in a tank.

I had only two gold fishes in my first ever fish bowl when I was a kid.

I started with one goldfish in a fishbowl. Then I added another one to give it a company. When I got my first aquarium, I added over a dozen fish.
