3 Gallon Tank

Discussion in 'Aquarium Stocking Questions' started by SourCream, Jun 6, 2016.

  1. 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.
