You visit an aquarium store for your first fish but you got confused about which fish to buy first. You are probably looking for your first fish species to be a hardy fish, don’t worry we have got you covered.
There are too many species to choose from. Many hardy fish are available in the local market depending on your aquarium setups.
Common goldfish or Shubunkin grows about 12 inches in the home aquarium. Goldfish produces a lot of waste so you should be having good filtration in your aquarium. One common goldfish per 20-30 gallon tank is enough. They are quite hardy and are adaptive to many water parameters and conditions. Goldfish loves to eat plants and algae so they are not made for your planted aquarium.
