    Is this big enough for fish? Can this be enough for the Nitrogen Cycle? Can this be a community tank for small fish?

    You can have a betta or shrimp but that's it for a community tank you need atleast a 20 long.

    You can have a community in a tank smaller than a 20 gal long, but agreed, in a 3 gal, you're limited to a betta and/or inverts like snails and shrimp.

    You can cycle a 3 gal successfully.

    I don't think its a good idea to do a community in something under 20 gallon,i would only do a species only tank.

    With a three gallon you are pretty limited to shrimp, snail, or betta tank. You can cycle a tank of any size though, just have to keep on the maintenance for a smaller tank.

    You might be able to do a two type of fish community in a ten gallon if you choose non schooling fish, or choose one schooling fish with tiny bioload, then a couple non schooling fish to go with that. You are pretty limited with a ten gallon community wise.

    For a more wider experience for a community twenty gallons and higher is highly recommended, as then you can do a fish that goes on the bottom like cory cats, as well as middle/top.

    You can definitely do a community in a 10 gal, you're just very limited on species options. Most people probably don't explore this option because the fish are hard to find and/or expensive.
