    Green? As in emerald green? Fun fact, emeralds aren't actually cories! They are a different species of catfish that very closely resembles cories. You will need to rehome them, or upgrade because they can reach 3-4 inches and need at least a 30-40g imo. Also They need to be in a school of 6+.
    Once you get rid of the cories, you are fully stocked because of the high bioload of platies. If you have good filtration and you rehome or return 2-3 platies, you can add a couple of other fish, depending on size and compatibility.

    A lot of people think they are cories. Maybe they were classified as cories when they were discovered?

    A good time of thumb for tank stocking is to calculate the surface area of the tank (length x wixth) in square inches. For every square inch of surface area, you can add 1 inch of fish. For example, if a fish is 6 inches long, it requires 6 square inches of surface area. Keep in mind that this is the adult size of the fish, not the size they are now.

    There are exceptions to this rule. Thin fish count for about half as much. Goldfish require more space than their size would suggest. Invertebrates like shrimp don't count. You can add extra fish if you have enough healthy greenery. But, overall, the rule works.

    Eh. There aren't really any good rules of thumb for stocking. Fish have such different requirements about space, compatibility, social requirements, etc. That you just have to research and research to figure out what works.

    I said it's a rule of thumb, not the fish stocking law. It's based on roughly how much air a fish of a given size uses.

    I understand that, but I don't agree that it works for stocking your tank.
