When most people think of goldfish they think of small fish bowls with a fish that was won at the fair.
This is not the correct way to house goldfish.

The minimum tank size for a goldfish is 20 gallons. You will also need a filter and to perform 10 to 15% weekly water changes there are many different varieties of goldfish and it’s fine to mix them as long as they aren’t breeds that would compete with each other for food.


For example keep single tailed varieties together and normal eyed goldfish together.

Growing to three to four inches (and larger), the most popular varieties include tiger barbs (puntigrus tetrazona), Odessa barbs (pethia padamya) and cherry barbs (puntius Titteya).


Some species are considered semi aggressive so we recommended buying 6 or more to reduce fin nipping.
Good tank mates include rasboras, tetras and corydoras.


But stay away from long finned fish like angelfish and Betta fish.

5. Corydoras

Cory catfish are peaceful schooling fish, much like Rasboras and tetras, but they dwell at the bottom of the Aquarium.

Kuhli Loaches (pangio kuhlii) will either fascinate or freak you out because they look like little 4 inches eels or snakes.
As nocturnal fish, they tend to be a little shy and hide behind d├ęcor, so keep them in groups of at least three to six so that they feel safe enough to come out and explore.


Like corydoras, these bottom dwellers scavenge for leftovers on the ground and between rocks, but you must specifically feed them to make sure they don’t go hungry.


Most popular species available in the freshwater aquarium can be as flamboyant and colorful as saltwater fish.
