Stocking Evenly
You need to get fish that swim at different tank levels. This way, there would be much less competition for space. There’s also the bonus of having an attractive tank filled with fish from top to bottom.
Fish Compatibility
Fish have different temperaments and personalities, much like we humans do. Some species may get along with each other, while others may not. If you see fish labeled as aggressive or semi-aggressive, it should be a good idea to place them in a tank with plenty of space. Also, make sure that two males aren’t in the same tank.
Installing Plants
You may have certain plants and other accessories in your tank. These may affect different fish species in different ways. Silver Dollars, for example, would nibble at almost any aquarium plant in next to no time. Goldfish and Oscars are even worse, even uprooting the plants completely.
