Thank youqchris87 said:Research, honestly. Seriously Fish is a great website that can help determine what a fishes requirements are including tank size, temperature range, food requirements, etc. You can also post on here in the stocking section. There are quite a few stocking lists on this website
For example: Stocking List for 10 Gallons
Another good website but slightly more focused is Planet Catfish.
That’s true. I’m a habitual rule breaker (of course, within reason) ops:. It works for me, but may not work for others. However, no one can tell me my stocking doesn’t work. Some will even allude that I replace my fish when they die because my stocking just isn’t possible. Now that **** me off, but I try not to take it personally.

The issue is, that someone who is even moderately experienced can keep way more than 13 neon tetras in a 20 gal. So once you get into the more nitty gritty of trying to really fill out a tank (if you want to go that way) then it changes a lotfjh said:Id like to disagree with what everyone is saying to provide another point of view.
The 1" per gallon is a rule of thumb. If a neon tetra is roughly 1.5", then you could fit 13 of them in a 20 gallon tank with no tankmates (for instance).
However, people should always research the fish before they buy. What are the aggressive/territorial needs? Are they messy eaters? Do they need others kf its kwn kind, or are they best kept alone? What are the minimum tank dimensions? Etc...
So although 13 1.5" neons will work in a 20g tank, 2 10" oscars is a bad choice. Really it comes down to common sense and research, and any "rule of thumb" breaks down when you look too closely.
