    Default how many fishes in 72L

    hello everyone
    Hello everyone!
    I am setting an 72L aquarium. It is my first one so I am getting some information about fishes and needed equipment. I also wanted to ask you about fishes. How many of them can I have in this tank? Maybe you have some examples of fishes easy to take care of? Thanks for every answer!

    Hello and welcome to the community! Usually, in a well-maintained aquarium, you should be able to have one inch of fish per gallon. One gallon is a little bit more than 3.5 liters so the maximum number of fish in a 72L aquarium would be: 19. I would recommend starting with half that many until your tank is well established. The easiest fish I have ever raised were Molies. They give live birth and seem to do well in cool to warm water. I'm sure lots of others can offer better advice about the kind of fish as my experience is limited with them. I usually just grow water plants in my aquarium and add in some fish for fun.
