Material
- Fish tanks come in various shapes and sizes. They may be round, square, oval, or triangular. Some are made out of plastic, others out of wood, and others out of metal. Whatever material they're made out of, fish tanks are designed to hold water so that fish can live in them. Fish tanks also serve another important function; they provide an environment where fish can grow and develop.
- Acrylic aquaria can be found in various sizes, shapes, and colors. They may also be made out of glass or plastic. Plastic containers are typicallyer than glass ones, although they do not last as long. Glass containers are generally heavier and thicker than plastic ones, so they are often used for larger fish tanks.
Number Of Fish
However, this expert rule is flawed because it doesn't consider factors such as growth rate, appetite, waste output, body type, or water surface area when making recommendations.
We suggest keeping one fish in a 5 gallon tank. This ensures they're comfortable and meet their environmental needs.

But first things first - decide what type of fish you'd like to keep (tropical community tank, cichlid setup, or salt water reef) and then think about the size of the tank you want.
