How many fish can go into a 2ft tank?

The number of fish that can comfortably live in a 2-foot tank depends on the species and their size. A general rule of thumb is to allow 1 inch of fish per gallon of water. For a 2-foot tank, which typically holds around 20-30 gallons, you could keep approximately 20-30 inches of fish total, but it's important to consider the specific needs of the species and the tank's filtration and aeration. Always prioritize the well-being of the fish over the quantity.
