Type of Fish Species<\/strong><\/p>\n

<\/p>\n

When it comes to owning fish tanks with different sizes, the type of fish you can use on a specific fish tank also varies. The smaller the fish tank you own, the more limitations you have in selecting different species of a fish tank.<\/p>\n

5 – Gallon Fish Tank<\/em><\/p>\n

If you have a 5-gallon fish tank, the number of fish you can put in the aquarium is around 4 to 6 fish. Actually, the general rule when stocking fish in your aquarium is one inch of fish per gallon of water. The recommendation earlier should be ideal for this type of fish tank, especially if you will be breeding smaller fishes. Fish that can grow up to 2 inches is not suitable for this fish tank size.<\/p>\n

If you ask me what fish can go in a 5 gallon tank, there are many of them that you can use. The fish species include guppies, betta fish, mollies, cherry shrimp, neon tetras, pygmy corydoras, harlequin rasbora, and neon tetras.<\/p>\n

10 – Gallon Fish Tank<\/em><\/p>\n

If you are using a 10-gallon fish tank, the ideal quantity of fish that you can put is 8 to 10 fish. However, a maximum of 10 must be avoided unless you are stocking small fish together. If you use fish that tends to grow over time, the limit should be around 6 to 8 fish.<\/p>\n

If you ask me what fish can live in a 10 gallon tank, there are many species to choose from. You can go for betta fish, guppies, dwarf gourami, golden dwarf barbs, neon tetras, zebra danios, mollies, cardinal tetras, and many more.<\/p>\n

20 -Gallon Fish Tank<\/em><\/p>\n

The 20-gallon fish tank is considered the standard when it comes to the sizing of the aquarium. Most experienced aquarists use this type of tank because the size is enough to stock an ideal quantity of fish.<\/p>\n

A 20-gallon fish tank can accommodate 20 1-inch fish or 10 2-inch fish. So, it all depends on the size of the fish you are stocking that determines the quantity you can use in every aquarium. You should also consider the ability of the fish to grow in the future as an added factor when determining the quantity of the fish.<\/p>\n

If you ask me what fish can live in a 20 gallon tank, there are many different types of fish that you can stock inside a 20-gallon fish tank. The fish species you can use include swordtail, neon tetra, zebra danio, guppies, catfish, mollies, rasboras, Apistogramma, german blue ram, and many others.<\/p>\n

Maintenance Challenges<\/strong><\/p>\n

The bigger the space, the more challenging it is to maintain a fish tank. It is the reason why I will recommend it to those who are just starting to use the smaller size of the fish tank. The cleaning and maintenance requirement is not that difficult compared to those with bigger dimensions.<\/p>\n

The maintenance activities you need to do are regular water changes, testing and monitoring water parameters, feeding, and managing light and the aquarium as a whole. All of these activities will be difficult once you are using a bigger type of fish tank.<\/p>\n

Price<\/strong><\/p>\n

Another key difference between these types of the fish tank is the price of each. Naturally, the bigger the size, the more expensive it is for its price point. The 20-gallon tank is more expensive compared to the other two, which are smaller.<\/p>\n
